Product details
Overview
AFBR-59SMI2Z from Broadcom is a 250-MBd full-duplex POF transceiver with integrated 650-nm LED transmitter and PIN photodiode receiver, operating at 3.3 V, supporting LVDS I/O, analog RSSI monitoring, and EMI-shielded SMI connector interface for industrial and medical data links up to 50 m over 1-mm-core polymer optical fiber.
For engineers reviewing the AFBR-59SMI2Z datasheet, pinout, applications, or equivalent options, key selection considerations include its 250-MBd data rate, –21 dBm receiver sensitivity, 3.3-V LVDS compatibility, RSSI analog monitor output, and EMI shield solder post grounding requirements.
Technical Context
The AFBR-59SMI2Z implements a fully integrated optical link architecture: the transmitter uses an LVDS-input driver IC modulating a 650-nm LED with typical 1.2-ns optical rise/fall times and 12-dB extinction ratio; the receiver delivers LVDS output with 500–800-mV differential swing and includes a linear RSSI current output proportional to average optical input power.
It operates across –40°C to +85°C, features automatic low-power sleep mode (wakes in ≤1.0 ms on valid optical signal), and achieves high EMI immunity via conductive plastic housing, dual EMI shield posts, and optimized ground return paths-validated per IEC 61000-4-3 (15 V/m, 8 MHz–1 GHz) and ESD22-A114 (2-kV HBM).

| 2, 3 | TD–, TD+ | LVDS differential transmitter input - accepts 200–1200-mV differential swing from PHY |
| 4, 6 | TGND | Transmitter ground reference - separate from receiver ground to minimize crosstalk |
| 5 | TVCC | Transmitter 3.3-V supply - requires local 10-μF + 10-nF decoupling |
| 7 | RVCC | Receiver 3.3-V supply - independent rail for noise isolation |
| 8 | RGND | Receiver ground reference - kept contiguous under module for low-inductance return path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar optical transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-59R5Z | Same SMI package but 125-MBd max rate; no RSSI output; lower ICC (18 mA typ.) | Suitable for cost-sensitive industrial networks with <125-MBd bandwidth needs | Select when RSSI monitoring and 250-MBd are not required - lower power and BOM cost |
| HFBR-5962L | Legacy Avago POF transceiver; 250-MBd; no EMI shield posts; different SMT footprint (14-pin) | Compatible with legacy board designs using HFBR-59xx footprint | Choose only for drop-in replacement on existing HFBR-5962L layouts - lacks EMI shield posts and RSSI |

FAQ
What is the maximum supported link distance for AFBR-59SMI2Z?
The AFBR-59SMI2Z supports up to 50 meters over standard 1-mm-core polymer optical fiber (POF) with 2.2-mm jacket, verified at 250 MBd under industrial temperature conditions (–40°C to +85°C). Performance assumes use of compliant POF cable and proper RSSI monitoring to confirm optical power margin.
Does AFBR-59SMI2Z require external biasing or termination resistors?
The AFBR-59SMI2Z integrates all necessary biasing circuitry. External 100-Ω differential termination is required on both TD+/- and RD+/- lines per LVDS standards. A 2-kΩ shunt resistor is recommended on the RSSI pin to convert current output to measurable voltage; no additional biasing components are needed for basic operation.
How does the RSSI output of AFBR-59SMI2Z function in practice?
The AFBR-59SMI2Z RSSI pin delivers a current output proportional to average optical input power (0.65 A/W). When loaded with a 2-kΩ resistor, it yields a linear voltage from 0 V to VCC – 1.5 V. For stable readings, a 100-nF capacitor across the resistor is recommended to filter high-frequency noise without affecting response time.
Can AFBR-59SMI2Z operate with 2.5-V or 5-V supply rails?
No - the AFBR-59SMI2Z is specified only for 3.0–3.6 V operation (typ. 3.3 V) on both TVCC and RVCC. Operation outside this range violates absolute maximum ratings and may cause permanent damage or undefined behavior. It is not compatible with 2.5-V or 5-V logic families without level-shifting.
What mechanical mounting requirements apply to AFBR-59SMI2Z?
The AFBR-59SMI2Z requires a PCB thickness of 1.57 mm ± 0.08 mm and recommends connecting both EMI shield solder posts (pins 1 and 12) directly to chassis or signal ground. The SMI connector must remain unobstructed; dust plug clearance is intentional and does not affect optical performance.
