Product details
Overview
AFBR-59E4APZ-HT from Broadcom is a multimode SFF transceiver for Fast Ethernet (100BASE-FX) operating over 62.5/125-μm and 50/125-μm fiber, featuring a 1310-nm LED transmitter, InGaAs PIN photodiode receiver, differential LVPECL I/O, single +3.3V supply, and –40°C to +95°C industrial temperature range.
For engineers reviewing the AFBR-59E4APZ-HT datasheet, pinout, applications, or equivalent options, key selection criteria include optical power budget (–20.0 to –14.0 dBm TX, –31 to –14 dBm RX), signal detect hysteresis (0.5–1.9 dB), LVPECL AC-coupled interface compatibility, and LC connector integration in a 2×5 DIP package.
Technical Context
The AFBR-59E4APZ-HT implements a fully integrated optical subassembly with an LED driver IC converting differential LVPECL inputs into analog LED current, and a receiver chain comprising an InGaAs PIN photodiode, transimpedance preamplifier, and quantizer IC delivering LVPECL data and single-ended signal detect outputs.
Its electrical subassembly uses a multilayer PCB with internal EMI shielding, isolated solder posts for mechanical anchoring, and housing leads tied to signal ground-designed to meet FCC Class B and CENELEC EN55022 radiated emissions limits with ≥10 dB margin while maintaining immunity to 10 V/m RF fields (80 MHz–1 GHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Standard | IEEE 802.3u 100BASE-FX compliant - ensures interoperability in Fast Ethernet networks using multimode fiber. |
| Optical Wavelength | 1270–1380 nm center - supports broad spectral tolerance across legacy and upgraded multimode links. |
| TX Output Power | –20.0 to –14.0 dBm (62.5/125 μm) - provides sufficient link budget for ≤2 km multimode reach at 100 Mbps. |
| RX Sensitivity | –31 dBm minimum input - enables reliable detection under low-light conditions including aging and splice loss. |
| Data Rate | 125 Mbaud (4B/5B encoded) - matches Fast Ethernet line rate with deterministic jitter performance (RJ < 0.69 ns TX, < 2.14 ns RX). |
| Supply Voltage | +3.0 to +3.6 V - compatible with standard 3.3V logic rails and tolerant of board-level regulation variation. |
| Signal Detect Hysteresis | 0.5–1.9 dB - prevents output chatter during marginal optical input transitions near –33 dBm assert level. |
Pinout & Package
AFBR-59E4APZ-HT uses a 2×5 DIP package with 10 signal pins and two isolated solder posts for mechanical mounting. The housing is molded nonconductive plastic; LC connector height complies with industry-standard panel cutouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Receiver Signal Ground (VEE RX) | Direct connection to receiver ground plane - minimizes noise coupling into high-gain transimpedance amplifier. |
| Pin 2 | Receiver Power Supply (VCC RX) | +3.3V supply filtered close to pin - critical for low-noise operation of PIN/preamplifier/quantizer chain. |
| Pin 3 | Signal Detect (SD) | LVPECL-compatible single-ended output - asserts high when optical input ≥ –33 dBm, deasserts low below –45 dBm. |
| Pin 4 / Pin 5 | RD− / RD+ | Differential LVPECL data output - AC-coupled, terminated internally; requires external 100Ω differential load. |
| Pin 6 | Transmitter Power Supply (VCC TX) | +3.3V supply filtered close to pin - stabilizes LED driver IC against supply-induced modulation noise. |
| Pin 7 | Transmitter Signal Ground (VEE TX) | Direct connection to transmitter ground plane - isolates high-current LED switching from sensitive receiver paths. |
| Pin 8 | NC | No internal connection - must remain unconnected per design; no pull-up/down or routing required. |
| Pin 9 / Pin 10 | TD+ / TD− | Differential LVPECL data input - AC-coupled; accepts 125-Mbaud signals with 0.4–1.6 Vpp differential swing. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multimode Fast Ethernet transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-59E4APZ | Same optical/electrical specs but rated for 0°C to +70°C commercial temperature range. | Limited to climate-controlled indoor networking gear; not qualified for extended industrial ambient. | Select AFBR-59E4APZ-HT when operating outside 0–70°C or requiring full industrial qualification. |
| AFBR-59E5APZ-HT | Identical package and pinout, but uses VCSEL instead of LED - higher speed margin and lower power (ICC TX typ. 65 mA vs. 80 mA). | Better suited for future-proofing or margin-critical links; not drop-in due to different optical rise/fall time (0.3 ns vs. 1.0 ns typical). | Choose AFBR-59E4APZ-HT where LED reliability, cost, and legacy multimode compatibility are prioritized over peak speed headroom. |
Compared with AFBR-59E4APZ-HT, AFBR-59E4APZ lacks extended temperature validation and fails under sustained thermal stress, while AFBR-59E5APZ-HT offers faster edge rates but introduces VCSEL-specific aging and modal noise considerations unsuitable for all 62.5/125-μm installations.

FAQ
What is the maximum supported fiber distance for AFBR-59E4APZ-HT in Fast Ethernet applications?
The AFBR-59E4APZ-HT supports up to 2 km over 62.5/125-μm multimode fiber and up to 500 m over 50/125-μm fiber at 100BASE-FX speeds, based on its optical power budget (–20.0 to –14.0 dBm TX, –31 dBm RX sensitivity) and IEEE 802.3u compliance. Link margin accounts for connector loss, splice degradation, and 1 dB LED aging over lifetime. Actual distance depends on installed fiber quality and splice count.
Does AFBR-59E4APZ-HT require external termination resistors for LVPECL interfaces?
Yes, AFBR-59E4APZ-HT requires external 100 Ω differential termination for both TD+/TD− inputs and RD+/RD− outputs, as its LVPECL signals are AC-coupled and lack internal termination. The datasheet recommends 2.7 kΩ pull-downs on TD+/TD− and 150 Ω series resistors on RD+/RD− when interfacing with common SerDes ICs. Improper termination causes signal integrity issues including jitter and BER degradation.
How does the signal detect (SD) function behave on AFBR-59E4APZ-HT?
The AFBR-59E4APZ-HT signal detect (SD) output is a single-ended LVPECL signal that asserts high (VCC – 0.88 to VCC – 1.02 V) when received optical power exceeds –33 dBm and deasserts low (VCC – 1.62 to VCC – 1.81 V) below –45 dBm, with 0.5–1.9 dB hysteresis to prevent oscillation. SD response time is ≤100 μs on assert and ≤350 μs on deassert, enabling fast link fault detection in network management systems.
Can AFBR-59E4APZ-HT be wave-soldered without damage?
Yes, AFBR-59E4APZ-HT is qualified for wave soldering at up to +260°C for 10 seconds (MSL-1), with protective LC receptacle plugs installed during processing. Its plastic housing, isolated solder posts, and internal EMI shielding maintain integrity through aqueous wash and thermal cycling. Post-solder cleaning must avoid solvent exposure to optical surfaces, and LC plugs must be removed only after full cool-down.
What regulatory certifications apply to AFBR-59E4APZ-HT?
AFBR-59E4APZ-HT carries UL/CSA Component Recognition (File E173874), TÜV certification (R 50236535 0003), RoHS Directive 2011/65/EU compliance, and meets FCC Class B and CENELEC EN55022 radiated emissions limits with ≥10 dB margin. It also passes JEDEC JESD22-A114 Class 2 ESD testing (2000–3999 V) and IEC 61000-4-2/3 immunity standards for system-level deployment.
