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 oper - ate with the avago technologies hfbr-14xxz 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 opti - cal signal to a digital output signal without the requisite for additional external circuitry. because of its integrated design, the receiver has very high emc resistance. a wide receiver dynamic range and high sensitivity over tempera - ture is achievable. the data rate typically goes from 100 kbd to 50 mbd. a monitor (rssi) output, which delivers an output current proportional to the average incoming light power, is available. for an almost noise-free rssi-signal smoothing compo - nents are recommended. a capacitor in parallel to the resistor on the rssi output reduces potential high fre - quency signal parts. the use of a single 100 nf capacitor for signal smoothing is sufcient in most common appli - cations, as shown in the recommended receiver circuitry section on page 4. if this rssi function is not required, the output pin can be left foating. the rssi-signal is derived from internal controlling loops; therefore, the typical time constant of pure rssi output current without an external flter can be up to 1 ms. this time constant also depends on the actual average incoming light power. 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 electrostatic discharge voltage capability esd hbm 2000 v note 2 electrostatic discharge voltage capability esd mm 400 v note 3 note: 1. 1.6 mm below seating plane. 2. esd capability for all pins hbm (human body model) according to jedec jesd22-a114. 3. esd capability for all pins mm (machine model) according to jedec jesd22-a115.
