Description
The AFBR-24x9Z series components provide cost effec - tive, high performance fiber optic communication links for information systems and industrial applications with link distances of up to 3 km. The receivers are directly compatible with popular “industry-standard” connectors: ST® and SMA. They are designed for use with 62.5/125 µm multi mode fiber.

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 flame retardant ULTEM® plastic (UL File #E121562). The receivers (suffix Z, TZ) are easily identified by the dark grey color connector port. A metal port option is also available (suffix 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 flexibility 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 sufficient to remove particles of dirt; methanol on a cotton swab also works well. AFBR-24x9xZ Low-Cost 50 MBd Receiver The AFBR-24x9xZ fiber optic receiver is designed to oper- ate with the Avago Technologies HFBR-14xxZ fiber optic transmitters and multimode glass fiber 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 sufficient 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 floating. The RSSI-signal is derived from internal controlling loops; therefore, the typical time constant of pure RSSI output current without an external filter can be up to 1 ms. This time constant also depends on the actual average incoming light power.

Typical data are at 25 °C, VCC = 5.0 V. 2. In recommended receiver circuit, with an optical signal from the recommended transmitter circuit, transmitted via 62.5/125 µm MM fiber. 3. Condition for sensitivity limit: Total Jitter ≤ 0.6 UI (unit intervals). 4. Verified with a PRBS7 signal with mark ratio = ½ running at 40 MBd. 5. Verified with a PRBS7 signal with mark ratio = ½ running at 50 MBd. 6. Verified with a jitter-free Manchester coded pseudo random sequence running at 20 MBd (~10 Mbit/s) as optical input signal. 7. The device does not support DC operation. Hence any static low or high at the input will cause an undefined output signal. 8. The RSSI current output has been verified with an external resistor RRSSI=2 kΩ 9. The PWD is valid for the receiver only, assuming an ideal 50% duty cycle optical input signal. PWD = PWOUT-AVG - PWIN-AVG Operation with unbalanced pattern (mark ratio ≠ 1/2 or DC ≠ 50%) will cause a higher PWD than what is specified in this table. Pin Description Pin Name Function Reference

- Pins 1, 4, 5 and 8 are connected together internally. The metal port option components (suffix MZ) have an internal electrical connection between the metal port and the four grounding pins 2. The data output provides an inverted signal, thus an electrical low in case of light on and vice versa. PIN NO. 1 INDICATOR BOTTOM VIEW
