GENERAL DESCRIPTION The TSA5515T is a single chip PLL frequency synthesizer designed for TV tuning systems. Control data is entered via the I2C-bus; five serial bytes are required to address the device, select the oscillator frequency, programme the three output ports and set the charge-pump current. A flag is set when the loop is "in-lock". Another flag is set when a power dip occurs on the supply line. These flags are read out of the TSA5515T on SDA line (one status byte) during a READ operation. The device has 4 programmable addresses, programmed by applying a specific voltage on the AS pin. The phase comparator operates at 7.8125 kHz when a 4 MHz crystal is used.

FUNCTIONAL DESCRIPTION For The TSA5515T is controlled via the two-wire programming, there is one module address (7 bits) and the R/W bit for selecting READ or WRITE mode. WRITE mode: R/W = 0 (see Table 1) After the address transmission (first byte), data bytes can be sent to the device. Four data bytes are needed to fully program the TSA5515T. The bus transceiver has an auto-increment facility, which permits the programming of the TSA5515T within one single transmission (address + 4 data bytes). The TSA5515T can also be partly programmed on the condition that the first data byte following the address is Table 1 Write data format MSB Address Programmable divider Programmable divider Charge-pump and test bits Output ports control bits 1 0 N7 1 P7 1 N14 N6 CP X 0 N13 N5 T1 X 0 N12 N4 T0 X 0 N11 N3 X X MA1 N10 N2 X P2 MA0 N9 N1 X P1 LSB 0 N8 N0 OS X A A A A A I2C-bus.

byte 2 or byte 4. The meaning of the bits in the data bytes is given in Table 1. The first bit of the first data byte transmitted indicates whether frequency data (first bit = 0) or charge pump and port information (first bit = 1) will follow. Until an I2C-bus STOP condition is sent by the controller, additional data bytes can be entered without the need to re-address the device. This allows a smooth frequency sweep for fine tuning. At power-on, the ports are set to the high impedance state. The 7.8125 kHz reference frequency is obtained by dividing the output of the 4 MHz crystal oscillator by 512. Because the input of the UHF/VHF signal is first divided by 8, the step size is 62.5 kHz. A 3.2 MHz crystal can offer a step size of 50 kHz.

READ mode: R/W = 1 (see Table 2) Data can be read out of the TSA5515T by setting the R/W bit to 1. After the slave address has been recognized, the TSA5515T generates an acknowledge pulse and the first data byte (status word) is transferred on the SDA line (MSB first). Data is valid on the SDA line during a high position of the SCL clock signal. A second data byte can be read out of the TSA5515T if the processor generates an acknowledge on the SDA line. End of transmission will occur if no acknowledge from the
TSA5515T
processor occurs. The TSA5515T will then release the data line to allow the processor to generate a STOP condition. The POR flag (power-on-reset) is set to 1 when VCC goes below 3 V and at power-on. It is reset when an end of data is detected by the TSA5515T (end of a READ sequence). Control of the loop is made possible with the in-lock flag FL, which indicates (FL = 1) when the loop is phase-locked.

MSB is transmitted first. Address selection (see Table 3) The module address contains programmable address bits (MA1 and MA0), which offer the possibility of having several synthesizers (up to 4) in one system. The relationship between MA1 and MA0 and the input voltage on AS input is given in Table 3.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all SO packages. 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. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering
TSA5515T
Wave soldering techniques can be used for all SO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end. 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. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) 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.
