Product details
Overview
AFBR-5803AQZ from Broadcom is a 1300-nm FDDI/ATM/100BASE-FX fiber optic transceiver in a 1×9 SIP package with duplex SC or ST interface, supporting 100 Mb/s to 125 Mbaud signaling over multimode fiber up to 2 km, compliant with ISO/IEC 9314-3:1990 and ANSI X3.166–1990, and operating across –40°C to +85°C.
For engineers reviewing the AFBR-5803AQZ datasheet, pinout, applications, or equivalent options, key selection considerations include its dual-voltage operation (3.135–3.5 V or 4.75–5.25 V), PECL-compatible differential data I/O, signal detect output, optical power budget for 2-km 62.5/125-µm fiber links, and industrial temperature range compliance.
Technical Context
The AFBR-5803AQZ integrates a 1300-nm InGaAsP LED transmitter and an InGaAs PIN photodiode receiver with transimpedance preamplifier and quantizer ICs, delivering differential PECL outputs referenced to +3.3 V or +5 V. Its optical subassembly is optimized for FDDI PMD, ATM UNI v3.0, and IEEE 802.3u 100BASE-FX physical layer conformance.
It operates within strict jitter allocations per Annex E of FDDI PMD/LCF-PMD standards, tolerates worst-case input electrical jitter at transmitter inputs and worst-case input optical jitter at receiver inputs, and maintains <1 dB LED aging over mission life-below the industry-standard 1.5 dB limit-enabling stable long-term link budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling Rate | 10–125 Mbaud: supports FDDI, ATM 100-Mb/s, and Fast Ethernet 100BASE-FX without performance penalty within full temp/voltage range. |
| Optical Wavelength | 1300 nm: enables low dispersion and high coupling efficiency into 62.5/125-µm and 50/125-µm multimode fiber. |
| Output Optical Power (BOL) | –19 to –14 dBm avg. (62.5/125 µm): provides ≥12 dB optical power budget at 2 km per FDDI PMD spec. |
| Receiver Sensitivity | –31 dBm (min detect), –45 dBm (logic "0" cutoff): ensures robust signal detect hysteresis and noise immunity. |
| Supply Voltage | 3.135–3.5 V or 4.75–5.25 V: dual-rail compatibility simplifies system power architecture and avoids level-shifting. |
| Operating Temperature | –40°C to +85°C: validated for industrial automation, substation, and HVDC environments with no derating. |
| Package Style | 1×9 SIP with duplex SC/ST receptacle: multisourced footprint enables board-level interchangeability and mechanical flexibility. |
Pinout & Package
AFBR-5803AQZ uses a standard 1×9 single-in-line package (SIP) with 9 signal pins and two isolated solder posts for mechanical anchoring. The package height complies with duplex SC connector clearance requirements (max 39.12 mm), and housing is molded nonconductive plastic with internal EMI shielding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VEE (Ground) | Common emitter reference for PECL I/O; electrically isolated from solder posts; requires local decoupling. |
| 2, 3 | Rx Data (RD) | Differential receiver output pair; PECL-compatible, terminated to VCC – 2 V via 50 Ω for signal integrity. |
| 4 | Signal Detect (SD) | Single-ended active-high output indicating valid optical input ≥ –31 dBm; hysteresis prevents chatter near threshold. |
| 5, 6 | VCC | Primary power supply pins; accept either 3.3 V or 5 V; require parallel 0.1 µF + 10 µF decoupling per datasheet Figure 9. |
| 7, 8 | Tx Data (TD) | Differential transmitter input pair; ECL-referenced, accepts –1.81 V to –0.88 V swing; drives LED via internal driver IC. |
Key Features
| Feature | Design Value |
|---|---|
| FDDI PMD Compliance | Meets ISO/IEC 9314-3:1990 and ANSI X3.166–1990 optical specs-enables drop-in use in certified FDDI backbone systems. |
| ATM & 100BASE-FX Support | Shares identical physical layer definition per ATM Forum UNI v3.0 and IEEE 802.3u-eliminates need for separate PHY designs. |
| Low LED Aging | <1 dB degradation over lifetime vs. industry-standard 1.5 dB-preserves optical margin and extends link reliability in 24/7 operation. |
| Dual-Voltage Operation | Validated at both 3.3 V and 5 V rails-supports legacy and modern host interfaces without external regulators or level shifters. |
| EMI-Optimized Packaging | Internal shields + nonconductive housing + isolated solder posts reduce emissions by 9–13 dB vs. FCC/CISPR Class B limits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fiber optic transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-5803ATQZ | Identical optical/electrical specs; differs only in date code marking and minor internal process revision-fully interchangeable per Broadcom documentation. | No functional difference; same FDDI/ATM/100BASE-FX support, 2-km reach, and industrial temp range. | Select AFBR-5803ATQZ when prioritizing latest production lot or specific traceability requirements. |
| HFBR-5803CPZ | Same 1×9 SIP package and 1300-nm LED/PIN architecture but rated for commercial temp (0°C to +70°C); lower max supply current (165 mA vs. 175 mA). | Limited to controlled-environment datacom applications; not qualified for factory floor or outdoor substation use. | Choose HFBR-5803CPZ only for cost-sensitive commercial gear where industrial temp range is unnecessary. |
Compared with AFBR-5803ATQZ, the AFBR-5803AQZ offers identical performance and form factor but distinct manufacturing traceability; versus HFBR-5803CPZ, it delivers verified –40°C to +85°C operation and tighter aging control-making it the sole choice for mission-critical industrial fiber links.

FAQ
What is the maximum supported fiber link distance for AFBR-5803AQZ?
The AFBR-5803AQZ is specified for 2-km multimode fiber backbone links using 62.5/125-µm fiber per FDDI PMD standards. Its optical power budget (≥12 dB at BOL) and receiver sensitivity (–31 dBm) are validated for this distance under worst-case modal dispersion and aging conditions. Performance beyond 2 km is not guaranteed and depends on fiber quality, splice count, and connector loss.
Does AFBR-5803AQZ support both 3.3 V and 5 V operation simultaneously?
No, AFBR-5803AQZ operates on a single supply rail: either 3.135–3.5 V or 4.75–5.25 V-not both. The device must be powered from one rail only; mixing voltages will damage the IC. Designers must select appropriate termination resistors (82 Ω or 130 Ω) per Figure 9 based on chosen VCC to maintain PECL signal integrity.
How does the signal detect function behave on AFBR-5803AQZ?
The AFBR-5803AQZ signal detect (SD) output is a single-ended, active-high PECL signal that asserts when input optical power exceeds –31 dBm and deasserts below –45 dBm, providing ≥14 dB hysteresis. Its maximum assertion time (AS–MAX) is 100 µs and deassertion time (ANS–MAX) is 350 µs-ensuring reliable detection without false triggers during brief optical interruptions.
Is AFBR-5803AQZ RoHS compliant and lead-free solder compatible?
Yes, AFBR-5803AQZ is RoHS compliant and qualified for lead-free soldering. Its solder posts feature Tin-Copper over Nickel plating, and electrical pins use pure Tin over Nickel plating-both compatible with standard wave solder and aqueous wash processes per datasheet Section 3. The device meets MIL-STD-883 Method 3015.4 Class 2 ESD rating.
Can AFBR-5803AQZ be used in 100BASE-FX applications without modification?
Yes, AFBR-5803AQZ is fully compliant with IEEE 802.3u 100BASE-FX because the standard explicitly adopts the FDDI PMD optical specification. Its 1300-nm wavelength, output power, extinction ratio, and jitter performance meet all mandatory 100BASE-FX physical layer requirements-no firmware, configuration, or external components are needed for interoperability.
