Product details
Overview
HFBR-5963ALZ from Broadcom is a multimode fiber optical transceiver for SONET OC-3/SDH STM-1 and Fast Ethernet physical layers, featuring 1300 nm InGaAsP LED transmitter, InGaAs PIN photodiode receiver, +3.3 V single-supply operation, –40 °C to +85 °C industrial temperature range, and LC fiber connector interface.
For engineers reviewing the HFBR-5963ALZ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical characteristics, optical performance specs, differential PECL-compatible I/O, signal detect TTL output, and validated use in telecom interconnects, enterprise backbone links, and industrial Ethernet infrastructure.
Technical Context
The HFBR-5963ALZ integrates a custom silicon LED driver IC converting differential PECL inputs (ECL-referenced to +3.3 V) into analog LED drive current, and a receiver chain comprising an InGaAs PIN photodiode, transimpedance preamplifier, and quantizer IC delivering differential PECL outputs and +3.3 V TTL signal detect. It operates over 62.5/125 µm and 50/125 µm multimode fiber with full compliance to IEEE 802.3u 100Base-FX, FDDI PMD, and ITU-T G.957 STM-1 standards.
Its 2 × 5 DIP package includes isolated solder posts for mechanical anchoring, internal EMI shielding for the receiver subassembly, and RoHS-compliant construction manufactured in an ISO 9001-certified facility. The transceiver supports wave solder and aqueous wash processes and meets MIL-STD-883C Class 2 ESD rating (2200 V on pins).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temperature | –40 °C to +85 °C case temperature - enables deployment in uncontrolled industrial enclosures and outdoor telecom cabinets without active thermal management. |
| Data Rate Support | 155.52 MBd (SONET OC-3/SDH STM-1) and 125 MBd (Fast Ethernet) - matches standard line rates without protocol translation or clock multiplication. |
| Optical Wavelength | 1270–1380 nm center wavelength - optimized for low dispersion in multimode fiber at 1300 nm window, supporting legacy FDDI and ATM infrastructures. |
| Transmitter Output Power | –19 dBm avg (BOL, 62.5/125 µm) - provides ≥12 dB optical power budget margin for ≤2 km multimode links per IEEE/FDDI specifications. |
| Receiver Sensitivity | –31 dBm avg (OC-3, eye center) - ensures reliable detection under worst-case jitter and aging conditions with >1 dB margin vs. industry 1.5 dB LED aging convention. |
| Signal Detect Output | +3.3 V TTL logic level - directly interfaces with FPGA GPIO or ASIC status monitoring without level-shifting circuitry. |
| Supply Voltage | +3.3 V ±10% - compatible with standard LDO-regulated digital supply rails and eliminates need for dual-voltage regulation. |
Pinout & Package
HFBR-5963ALZ uses a 2 × 5 DIP package with 10 signal pins and two isolated solder posts for mechanical mounting. The housing is molded nonconductive plastic with integrated LC receptacle; maximum height complies with LC connector clearance requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | VEE RX | Receiver signal ground - must connect directly to contiguous receiver ground plane to minimize noise coupling into high-gain transimpedance amplifier. |
| Pin 2 | VCC RX | Receiver +3.3 V supply - requires local 10 µF + 10 nF decoupling placed within 5 mm to suppress switching noise from quantizer IC. |
| Pin 3 | SD | Signal detect TTL output - asserts high (>2.2 V) when received optical power exceeds –31 dBm; deasserts low (<0.6 V) below –45 dBm with 1.5 dB hysteresis. |
| Pin 4 | RD– | Receiver differential data out (complement) - PECL-compatible, requires external 50 Ω termination to VCC – 2 V for proper logic levels and impedance matching. |
| Pin 5 | RD+ | Receiver differential data out (true) - used with RD– to reject common-mode noise on long PCB traces or backplanes. |
| Pin 6 | VCC TX | Transmitter +3.3 V supply - separate rail from VCC RX allows independent filtering and reduces crosstalk between transmit and receive paths. |
| Pin 7 | VEE TX | Transmitter signal ground - isolated from VEE RX to prevent ground bounce coupling from LED driver switching current. |
| Pin 8 | NC | No connection - must remain unconnected; no internal circuitry or test function attached. |
| Pin 9 | TD+ | Transmitter differential data in (true) - accepts PECL-level input referenced to +3.3 V; no internal termination - external 50 Ω required. |
| Pin 10 | TD– | Transmitter differential data in (complement) - paired with TD+ to maintain signal integrity and enable common-mode rejection of board-level noise. |
Key Features
| Feature | Design Value |
|---|---|
| 1300 nm LED with <1 dB aging | Extends link reliability beyond 10-year equipment life without optical power recalibration or margin erosion. |
| Integrated EMI shielding | Prevents radiated emissions from receiver subassembly exceeding FCC Class B limits by ≥10 dB in open-board testing. |
| LC connector with process plug | Protects optical surfaces during wave soldering and aqueous cleaning; plug removal post-assembly prevents contamination. |
| Differential PECL I/O | Enables >100 MHz data transmission over >15 cm PCB traces with <0.5 ns p-p jitter contribution from transceiver alone. |
| –40 °C to +85 °C operation | Validated across full temperature range for both transmitter optical output stability and receiver sensitivity degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar optical transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HFBR-5963LZ | 0 °C to +70 °C operating range; otherwise identical optical/electrical specs and pinout. | Limited to commercial indoor environments; unsuitable for industrial control cabinets or outdoor telecom shelters. | Select HFBR-5963LZ only when ambient temperature remains within 0–70 °C and cost optimization is prioritized. |
| AFBR-5963Z | Same 2 × 5 DIP package and LC interface but uses VCSEL transmitter (850 nm) instead of 1300 nm LED; higher bandwidth but shorter reach. | Optimized for 100Base-SX (550 m over 62.5/125 µm); not compliant with SONET OC-3 or FDDI PMD standards. | Choose AFBR-5963Z only for short-reach Fast Ethernet where 850 nm VCSEL advantages outweigh loss of OC-3/FDDI compatibility. |
Compared with HFBR-5963LZ, the HFBR-5963ALZ adds extended temperature capability without trade-offs in optical budget or jitter; compared with AFBR-5963Z, it sacrifices 850 nm VCSEL bandwidth for guaranteed SONET/FDDI/100Base-FX interoperability and longer multimode reach.

FAQ
What is the maximum supported fiber distance for HFBR-5963ALZ in Fast Ethernet applications?
The HFBR-5963ALZ supports up to 2 km over 62.5/125 µm multimode fiber in Fast Ethernet mode, based on its –31 dBm receiver sensitivity, –19 dBm transmitter output, and 12 dB minimum optical power budget - meeting IEEE 802.3u 100Base-FX requirements without repeaters or amplifiers. Performance assumes standard 2.5 dB/km fiber loss and 0.5 dB per connector pair.
Does HFBR-5963ALZ require external termination resistors?
Yes, HFBR-5963ALZ requires external 50 Ω terminations on all differential I/O lines: TD+, TD–, RD+, and RD–. These must connect to VCC – 2 V (i.e., +1.3 V) to establish correct PECL logic thresholds. The signal detect (SD) output uses a 4.7 kΩ pull-up to VCC and 50 Ω series termination, as specified in Figure 3 of the AV02-1088EN datasheet.
Is HFBR-5963ALZ compatible with SONET OC-3 equipment using legacy FDDI fiber plant?
Yes, HFBR-5963ALZ is fully compliant with both ITU-T G.957 STM-1 and ISO/IEC 9314-3 FDDI PMD standards. It operates over the same 62.5/125 µm multimode fiber with NA = 0.275 used in FDDI installations and delivers the required –31 dBm sensitivity and 1.2 ns p-p systematic jitter to interoperate with OC-3 line cards and FDDI concentrators without protocol conversion.
How does the signal detect (SD) function behave across temperature for HFBR-5963ALZ?
The HFBR-5963ALZ signal detect (SD) output maintains consistent hysteresis (1.5 dB) and threshold accuracy (–31 dBm assert / –45 dBm deassert) across its full –40 °C to +85 °C operating range. This is validated per the receiver optical characteristics table in AV02-1088EN, ensuring reliable link status reporting in industrial thermal environments without recalibration.
Can HFBR-5963ALZ be used in place of HFBR-5963LZ without hardware changes?
Yes, HFBR-5963ALZ is a direct drop-in replacement for HFBR-5963LZ: identical 2 × 5 DIP package, pinout, electrical characteristics, and optical performance - differing only in qualified temperature range (–40 °C to +85 °C vs. 0 °C to +70 °C). No PCB layout, firmware, or schematic modifications are required for upgrade.
