2003 jun 03 9 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 7 functional description 7.1 rf data processing the rf data path is a fully dc-coupled, multi-stage amplifier (see fig.3). the input signal for data can be selected from rf inputs a to d or from the summed rf inputs rfsump and rfsumn. switching between the two sets of signals is performed by an internal multiplexer. the signals are fully balanced internally to improve signal quality and reduce power supply interference. rf outputs rfp and rfn can be dc coupled to the analog-to-digital converter (adc) of the decoder. the rf input signals are from photodiodes and have a large dc content by nature. this dc component must be removed from the signals for good system performance. built-in dacs, located after the input stages g 1 and rfsum, have the ability to do this. the dac range and resolution is scaled with the gain setting of the first amplifier stage. when the dc content is removed, the rf signal can be dc coupled to the decoder. the main advantage of dc coupling is fast recovery from signal swings due to disc defects since there is no ac coupling capacitance to slow the recovery. when using dc coupling, both ac and dc content in the data signal is known. the philips iguana decoders have on-chip control loops to support automatic gain control (agc) and dc cancellation. two separate dacs are available for cases where the left and right side dc conditions can be different. when it is not possible to have a dc connection between the TZA1035HL and the decoder, the signals on servo outputs oa to od can be used as they contain the same lp-filtered and dc coupled information. summing of the photodiode signals a to d is performed in the second amplifier stage g 2 . each individual diode channel can be switched on, off or inverted with switches sw-a to sw-d. switching between photodiode signals and rfsum input is performed immediately before the third amplifier stage g 3 . this stage has a variable gain with fine resolution to allow automatic gain adjustment to be controlled by the decoder. the filter stage limits the bandwidth according to the maximum playback speed of the disc. this is to optimize the noise performance. the filter stage consists of an equalizer and a noise filter, both of which can be bypassed, also the boost factor of the equalizer can be set. the corner frequencies of the equalizer and noise filter are equal and can be programmed to a 7-bit resolution. the rf output signals rfp and rfn can be dc coupled to a decoder with a differential input pair (as with philips iguana decoders). the common mode output voltage can be set externally at pin rfref. the signals for differential phase detection are tapped from the inputs a to d at the rf amplifier g 1 stages. dc cancellation for the a to d and rfsum signal paths can be set independently or simultaneously.

2003 jun 03 11 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 7.2 servo signal processing the photodiode configurations and naming conventions are shown in figs 4 and 5. 7.2.1 s ervo signal path set - up a block diagram of the servo signal path is shown in fig.6. in general, the servo signal path comprises: a voltage-to-current converter with programmable offset voltage source v lfoffs that is common to all inputs a 4-bit dac for each of the six channels to compensate for offset per channel a variable gain stage to adapt the signal level to the specific pick-up and disc properties low-pass filtering and output stage for the photodiode current signals error output stage in the radial data path for fast track counting. servo output signals oa to od, s1 and s2 are unipolar current signals which represent the low-pass filtered photodiode signals. in dpd radial tracking, the s1 and s2 signals are the equivalent of the satellite signals commonly found in traditional cd systems. the servo output signals oa to od, s1 and s2 are set to 3-state if bit rfonly = 1 (register 13, bit 11). 7.2.2 f ocus servo focus information is reflected in the four outputs oa to od. gain and offset can be programmed. for optical pick-ups where only channels b and c are used for focus, channels a and d can be switched off (bit focus_mode = 0). for initial alignment, a copy of the output currents can be made available on pin ocentral. 7.2.3 r adial servo radial information can be obtained from the two output signals s1 and s2, and the gain and offset can be programmed. the TZA1035HL provides differential phase detection, push-pull and three-beam push-pull for radial tracking. the signal ftc is made available for fast track counting and is primarily the voltage error signal derived from signals s1 or s2. the polarity of the radial loop can be reversed via the serial control bus (rad_pol). mgw553 handbook, halfpage tangential direction left right c d b a data=a+b+c+d push-pull = (a + b) - (c + d) focus = (a + c) - (b + d) dpd2 = phase (a + b, c + d) dpd4 = phase (a,d) + phase (c,b) fig.4 astigmatic diode configuration. fig.5 foucault diode configuration. data=a+b+c+d push-pull = a - d focus = c - b dpd2 = phase (a, d) dpd4 not applicable mgw554 handbook, halfpage tangential direction left right d c b a

2003 jun 03 13 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 7.2.4 d ifferential phase detection the TZA1035HL provides differential phase detection to support dvd in various ways: dpd2 with four channels programmed to be active gives dpd as required in the standard specification two of the four channels can be excluded from the dpd for pick-ups with an alternative photodiode arrangement an increase in performance, dedicated for dvd+rw, can be obtained by using the dpd4 method. then two truly separated phase detectors are active. after the phase detection of the two input pairs the result is summed. input signals for dpd are taken from input pins a to d after the first gain stage g 1 (see fig.3). pre-emphasis is applied by means of a programmable lead/lag filter. additionally, a programmable low-pass filter is available to improve the signal quality under noisy signal conditions at lower speeds. for further signal improvements the dpd pulse stretcher can be programmed to higher values at lower speeds. the dpd signal is low-pass filtered by two internal capacitors. the signal is then fed to pins s1 and s2, or directed via the drop-out concealment circuit to the outputs (see section 7.5). 7.2.4.1 drop-out concealment a special function is built in for compatibility with drop-out detection strategies, based on level detection in the s1 and s2 signals. when using dpd in a fundamental way, there is no representation of mirror level information from the light pen. when the drop-out concealment function is enabled (bit docen = 1), a portion of the central aperture (ca) signal is added to s1 and s2. also, when the ca signal drops below the doc threshold, the dpd signal is gradually attenuated. the dpd detection cannot work properly when the input signal becomes very small. the output of the dpd may then show a significant offset. the doc may not conceal this offset completely because: doc is gradually controlled from the ca signal the ca signal may not become 0 during disc-defect. for details see section 7.5.5.2 7.2.4.2 push-pull and three-beam push-pull the TZA1035HL can also provide radial information by means of push-pull signals (from the photodiode inputs) or in a three-spot optical system with three-beam push-pull (tbpp). the built-in multiplexer gives a flexible method of dealing with many detector arrangements. for push-pull, the input signals are taken from channels a to d. there is also a command that switches off channels b and c, leaving channels a and d for push-pull (bits rt_mode[2:0]). for tbpp, the input signal is taken from channels e and f, irrespective of bit rfsum setting. 7.2.4.3 enhanced push-pull (dynamic offset compensation for beam landing) this option cancels offsets due to beam landing. a factor a can be programmed to re-balance the signal gain between channels s1 and s2. in a simplified form this can be described as: s1 = a lfr a input left s2 = a lfr (2 -a ) input right. factor a can be programmed in a range from 0.6 to 1.35, with 1.0 as the balanced condition (bits a [3:0]). 7.2.4.4 offset compensation a provision is made to compensate electrical offset from a light pen. the offset voltage from the light pen can be positive or negative. in general, the offset between any two channels is smaller than the absolute offsets. as negative input signals cannot be handled by the TZA1035HL internal servo channels, a two-step approach is adopted: a coarse dac, common to all the input channels, adds an offset that shifts the input signals in positive direction until all inputs are 3 0. the dac used (lf offs ) has a 2-bit resolution (bits lf off [1:0]). a fine setting per channel is provided to cancel the remainder of the offset between the channels. this is achieved by dacs subtracting the dc component from the signals and bringing the inputs to approximately zero offset (within ? 1 mv). the dacs (registers 11 to 13) have a 4-bit resolution. the range of both dacs can be increased by a factor of three to compensate for higher offset values by means of control parameter bit servoos. with a switched-off laser, the result of the offset cancellation can be observed at each corresponding output pin, oa to od, s1 and s2, or via a built-in multiplexer to pin ocentral (central channels only). see registers 11 to 13 for dac and multiplexer control.
2003 jun 03 14 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 7.2.5 a utomatic dual laser supply the TZA1035HL can control the output power of two lasers; it has an automatic laser power control (alpc) that stabilizes the laser output power and compensates the effects of temperature and ageing of the laser. alpc automatically detects if there is a p-type or n-type monitor diode in use in either of the laser circuits. the regulation loop formed by the alpc, the laser, the monitor diode and the associated adjustment resistor will settle at the monitor input voltage. the monitor input voltage can be programmed to high ( ? 180 mv) or low ( ? 150 mv), according to frequently-used pre-adjustments of the light pen. this set point can be set independently for both alpcs. bandwidth limitation and smooth switch-on behaviour is realized using an internal capacitor. a protection circuit is included to prevent laser damage due to dips in laser supply voltage v ddl . if a supply voltage dip occurs, the output can saturate and restrict the required laser current. without the protection circuit, the alpc would try to maximize the output power with destructive results for the laser when the supply voltage recovers. the protection circuit monitors the supply voltage and shuts off the laser when the voltage drops below a safe value. the alpc recovers automatically after the dip has passed. only one laser can be activated at the same time. an internal break-before-make circuit ensures safe start-up for the laser when a toggle situation between the two lasers is detected. when both lasers are programmed on, neither laser will be activated. 7.2.6 p ower - on reset and general power on when the supply voltage is switched on, bit pwron is reset by the power-on reset (por) signal. this concludes in a standby mode at power up. por is intended to prevent the lasers being damaged due to random settings. all other functions may be switched when power is on. the TZA1035HL becomes active when bit pwron = 1. 7.2.7 c ompatibility with tza1033hl/v1 7.2.7.1 software compatibility the TZA1035HL is highly software compatible with the tza1033hl/v1. provided that some conditions are met, the software the TZA1035HL can be used as a successor with just minor modifications. this compatibility is achieved with the implementation of the TZA1035HL mode control bit (bit k2_mode). when bit k2_mode = 0, the TZA1035HL will act as a tza1033hl/v1. when bit k2_mode = 1, the TZA1035HL will act as a tza1033hl/k2 and the new functions will be available (but require a software update). other conditions or restrictions are: register bits of the TZA1035HL which were not defined are programmed to a logic 0. registers 9, 10, 14 and 15 may be left undefined the g 4 stage high gain setting of the tza1033hl/v1 is not available in the TZA1035HL; if this value was set to logic 0, there will be no difference when bit k2_mode = 0 the rf bandwidth will be fixed to the minimum value of 10 mhz (typical); bit k2_mode = 1 to select a higher bandwidth; the bandwidth is now lower than using a tza1033hl/v1. 7.2.7.2 hardware compatibility the package is changed from lqfp64 for the tza1033hl to lqfp48 for the TZA1035HL. the hardware differences are: input pins stb, header and land of the tza1033hl are not present input pins cd of tza1033hl/v1 are not used; TZA1035HL has rfsum inputs instead; the rfsum inputs of TZA1035HL may be connected to ground when not used.
2003 jun 03 15 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 7.2.8 i nterface to the system controller programming the registers of TZA1035HL is done via a serial bus (see fig.7). the circuitry is formed by a serial input shift register and a number of registers that store the data. the registers can always be programmed, irrespective of standby mode. if required, the bus lines can be connected in parallel with an i 2 c-bus. the protocol needs no switching of the data line during sicl = high. this means that other i 2 c-bus devices will not recognise any start or stop commands. control words addressed to TZA1035HL should go uniquely with the sild signal. when sild = high, the TZA1035HL will not respond to any signal on sida or sicl. during a transmission, the serial data is first stored in an input shift register. at the rising edge of sild, the content of the input register is copied into the addressed register. this is also the moment the programmed information becomes effective. the input pins have cmos compatible threshold levels for both 3.3 and 5 v supplies. handbook, full pagewidth mgw496 t load(h) sicl sida sild a3 d0 d1 d2 d3 d4 d5 d7 d8 d9 d10 d6 d11 a0 a1 a2 d0 d1 d2 d3 a2 a1 d4 a3 fig.7 two word transmission. 7.3 control registers the TZA1035HL is controlled by serial registers. to keep programming fast and efficient, the control bits are sent in 16-bit words. four bits of the word are used for the address and for each address there are 12 data bits. table 1 overview of control parameters symbol parameter values register bits data path g 1 (a 1 ) gain of ?rst rf ampli?er stage (or linear ampli?cation) 0, 6 and 12 db (1 , 2 and 4 ) 3 11 and 10 g 2 (a 2 ) gain of second rf ampli?er stage (or linear ampli?cation) 6, 12, 18 and 24 db (2 , 4 , 8 and 16 ) 3 9 and 8 g 3 (a 3 ) gain of third rf ampli?er stage (or linear ampli?cation) 0 to 13 db in steps of 0.8 db (1 to 4 )3 7to4 grfsum (a rfsum ) gain of rfsum input stage (or linear ampli?cation) - 6, 0, 6, 12 and 18 db (0.5 ,1 ,2 ,4 and 8 ) 0 7 to 5 bwrf bandwidth limitation in rf path f 0(rf) = 12 to 145 mhz 14 6 to 0

2003 jun 03 28 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL the bandwidth of the dpd signal is limited by the 100 khz phase detector integration filters and the bandwidth of the output stages (100 khz for s1 and s2). the input signals used for dpd depend on the programmed radial tracking mode (bits rt_mode[2:0]): dpd mode = dpd2: (a,d) or dpd2: (a + c ,b+d) dpd mode = dpd4: 0.5[ (a,d) + (c,b)] range of is from - 0.5 to + 0.5. > 0 if a,c phase leads with respect to d,b phase. ftc = (s1 - s2) (r ftc + ftcref) for s1 and s2 bit rad_pol is assumed to be set to logic 1. otherwise the signals appearing at s1 and s2 will be swapped. 7.5.5.2 dpd signals (dvd-rom mode) with drop-out concealment with bit docen = 1, drop-out concealment is activated and the s1 and s2 outputs change: the common mode level (i refrad ) is now determined by the ca signal the scaling changes. at low signal levels (sum < doc threshold ), the contribution of is reduced smoothly. s1 dpd =c i (fs)(dpd)(doc) + 0.25 ca. s2 dpd = - c i (fs)(dpd)(doc) + 0.25 ca. where: i (fs)(dpd)(doc) is the full scale range c = concealment multiplier, c = 0 to 1 when ca is 0 to doc threshold ca=oa+ob+oc+od doc threshold is typically 3 m a. for s1 and s2 bit rad_pol is assumed to be set to logic 1. otherwise the signals appearing at s1 and s2 will be swapped. the dpd detection can not work properly when the input signal becomes very small. the output of the dpd may then show a significant offset. the doc may not conceal this offset completely because: doc is gradually controlled from the ca signal the ca signal may not become 0 during disc-defect. 7.5.5.3 three-beam push-pull (cd mode) when the three-beam system is used, the radial signals s1 and s2 can be composed from inputs e and f. ftc = (s1 - s2) r ftc + ftcref (bandwidth limited to 600 khz). for s1 and s2 bit rad_pol is assumed to be set to logic 1. otherwise the signals appearing at s1 and s2 will be swapped. 7.5.5.4 enhanced push-pull top hold push-pull method is supported but only in conjunction with a compatible decoder. the peak hold function is executed in the decoder, by measuring the mirror levels of the gap-zones in each header. the TZA1035HL will compensate for offset errors in two ways: the dc offset from the pick-up can be compensated by means of a dac (c offsx ) in each channel the dynamic offsets can be compensated by means of the multiplier ratio a . the correction values must be calculated in the decoder and programmed via the serial bus. the method is called the enhanced push-pull method. for s1 and s2 bit rad_pol is assumed to be set to logic 1. otherwise the signals appearing at s1 and s2 will be swapped. d t t p ------ d t t p ------ d t t p ------ d t t p ------ d t t p ------ d t t p ------ d t t p ------ d t t p ------ d t t p ------ s1 pp a lfr e opuref C lf offs r offse ++ r lfr ----------------------------------------------------------------------------------------- ?t y = s2 pp a lfr f opuref C lf offs r offsf C + r lfr ---------------------------------------------------------------------------------------- ?t y =

2003 jun 03 42 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 13 soldering 13.1 introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering can still be used for certain surface mount ics, but it is not suitable for fine pitch smds. in these situations reflow soldering is recommended. 13.2 re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 270 c depending on solder paste material. the top-surface temperature of the packages should preferably be kept: below 220 c (snpb process) or below 245 c (pb-free process) C for all bga and ssop-t packages C for packages with a thickness 3 2.5 mm C for packages with a thickness < 2.5 mm and a volume 3 350 mm 3 so called thick/large packages. below 235 c (snpb process) or below 260 c (pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm 3 so called small/thin packages. moisture sensitivity precautions, as indicated on packing, must be respected at all times. 13.3 wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 c or 265 c, depending on solder material applied, snpb or pb-free respectively. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 13.4 manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
2003 jun 03 43 philips semiconductors preliminary speci?cation high speed advanced analog dvd signal processor and laser supply TZA1035HL 13.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales office. 2. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 3. these transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the reflow oven. the package body peak temperature must be kept as low as possible. 4. these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 6. wave soldering is suitable for lqfp, tqfp and qfp packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package (1) soldering method wave reflow (2) bga, lbga, lfbga, sqfp, ssop-t (3) , tfbga, vfbga not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hsqfp, hsop, htqfp, htssop, hvqfn, hvson, sms not suitable (4) suitable plcc (5) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (5)(6) suitable ssop, tssop, vso, vssop not recommended (7) suitable
