2 package and handling information package information the receiver is housed in a low-cost, dual-inline package that is made of high strength, heat resistant, chemically resistant, and ul 94v-o fame retardant ultem? plastic (ul file #e121562). the receivers (sufx z, tz) are easily identifed by the dark grey color connector port. a metal port option is also available (sufx mz). the metal port op - tion components have an internal electrical connection between the metal port and the four grounding pins, as shown in the package outline drawing. signal ground is separate from the four grounding pins to give fexibility in connecting the port to signal or chassis ground. the pack - age is designed for auto-insertion and wave soldering so it is ideal for high volume production applications. handling and design information each part is delivered with a protective port cap or a plug covering the optics. these caps/plugs will vary by port style. when soldering, it is advisable to leave the protec - tive cap on the unit to keep the optics clean. good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. clean compressed air often is sufcient to remove particles of dirt; methanol on a cotton swab also works well. afbr-24x9xz low-cost 50 mbd receiver description the afbr-24x9xz fber optic receiver is designed to op - erate with the avago technologies hfbr-14xxz/-1712tz fber optic transmitters and multimode glass fber cable. consistent coupling into the receiver is assured by the optical system with lens. the receiver output is a digital cmos/ttl signal. the afbr-24x9xz receiver contains an ic with integrated photodiode which directly converts the incoming optical signal to a digital output signal without the requisite for additional external circuitry. because of its integrated design, the receiver has very high emc resis - tance. a wide receiver dynamic range and high sensitiv - ity over temperature is achievable. the data rate typically goes from 100kbd to 50mbd. a monitor (rssi) output, which delivers an output current proportional to the aver - age incoming light power, is available. absolute maximum ratings parameter symbol min max unit reference storage temperature t s -40 +85 c operating temperature t a -40 +85 c supply voltage v cc -0.3 5.5 v maximum dc output current i o 10 ma voltage at rssi output v rssi -0.3 v cc +0.3 v lead soldering cycle - temp t sold 260 c note 1 lead soldering cycle - time t sold 10 s note 1 note 1. 6 mm below seating plane. www.datasheet.net/ datasheet pdf - http://www..co.kr/

4 notes 1. the value of r rssi has to be chosen according to the particular optical power situation in order to provide a suitable monitoring voltage. for the characterization of the responsivity 2 k were used. the lower the power the higher the resistor value should be. however the max. limit of v rssi should not be overridden. recommended receiver circuitry figure 1. typical rssi output voltage across r rssi = 2 k 1e-01 1e+00 1e+01 1e+02 1e+03 1e+04 -30 -20 -10 0 v rssi - mv p in - optical input power - dbm 85c 25c -40c recommended transmitter driver circuitry using either hfbr-14x4xxz or hfbr-1712tz note: 1. subsequent resistor/capacitor values have been used during the characterization: transmitter r1 r2 r3 c3 hfbr-14x4xxz 50 50 75 75 pf hfbr-1712tz 33 300 270 0 data connect either hfbr-14x4xxz or hfbr-1712tz 74actq00mtc gnd gnd txvcc 10uf 100uf gnd gnd gnd hfbr-14x4xxz an2 2 an7 7 cat 3 1 an6 6 4 5 8 1 2 3 ic1a 4 5 6 ic1b 9 10 8 ic1c 12 13 11 ic1d r3 r1 r2 c3 c1 c2 hfbr-1712tz an 6 7 cat 3 1 2 4 5 8 ll tx ll tx monitoring phy 10uf 2k 1uh gnd 100uf gnd gnd gnd gnd rxvcc vcc 3 /do 2 gnd 7 1 rssi 6 4 5 8 afbr-24x9xz c1 r_rssi l1 c2 v_rssi /do ll rx www.datasheet.net/ datasheet pdf - http://www..co.kr/
