Product details
Overview
AFBR-5813QZ from Broadcom is a 125-Mbaud Fast Ethernet optical transceiver in a 1×9 package with duplex SC connector, featuring 1300-nm InGaP LED transmitter and InGaAs PIN photodiode receiver, operating over multimode fiber up to 2 km, compliant with IEEE 802.3u 100BASE-FX and FDDI standards.
For engineers reviewing the AFBR-5813QZ datasheet, pinout, applications, or equivalent options, this transceiver delivers deterministic signal detect timing (≤100 μs assert), LVPECL-compatible differential I/O, industrial temperature operation (–40°C to +85°C), and RoHS-compliant 3.3V single-supply functionality for fiber backbone and media converter designs.
Technical Context
The AFBR-5813QZ integrates an AC-coupled, internally terminated LVPECL input stage driving a 1300-nm surface-emitting InGaP LED, with optical output power ranging from –23.5 dBm (50/125-μm) to –17 dBm (62.5/125-μm) at end-of-life. Its receiver uses an InGaAs PIN photodiode paired with a transimpedance amplifier and quantizer, delivering LVPECL differential data output and single-ended signal detect (SD) with hysteresis of ≥1.5 dB between –33 dBm (assert) and –45 dBm (deassert).
No digital diagnostic interface (DMI) is present - unlike the 2×9 AFBR-5823xxZ variants, the AFBR-5813QZ lacks SFF-8472 compliance, EEPROM, SDA/SCL pins, or Tx_Disable functionality; all monitoring and control remain analog-only via SD, RD+/RD–, and TD+/TD– signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling Rate | 125 Mbaud - supports full-duplex 100BASE-FX Fast Ethernet without autonegotiation pulses |
| Operating Temperature | –40°C to +85°C - enables deployment in uncontrolled industrial environments without thermal derating |
| Supply Voltage | 3.13 V to 3.47 V - tight 3.3V tolerance ensures stable operation with standard LDO regulators |
| Optical Input Sensitivity | –31 dBm - minimum average power required for BER < 1×10⁻¹⁰ on 62.5/125-μm fiber |
| Signal Detect Timing | t_sd_on ≤ 100 μs - guarantees rapid link-up detection after optical signal arrival |
| Transmitter Output Power | –20 dBm (typ.) on 62.5/125-μm fiber - meets 100BASE-FX power budget for ≤2 km links |
| Receiver Output Interface | Differential LVPECL - compatible with standard PECL receivers requiring 100 Ω termination |
Pinout & Package
AFBR-5813QZ uses a 1×9 single-in-line package with 9 signal pins and 2 mechanical solder posts; the housing incorporates a duplex SC receptacle and conforms to multisource 1×9 SIP dimensions (39.3 mm × 12.7 mm × 9.4 mm). No DMI-related pins (SDA/SCL/Tx_Disable) are present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VEER | Receiver ground | Direct connection to host board ground plane; low-inductance return path for Rx IC |
| 2 RD+ | Receiver data out (+) | LVPECL differential output requiring 100 Ω termination to VCC–2 V |
| 3 RD– | Receiver data out (–) | Complementary LVPECL output paired with RD+ for noise-immune signal recovery |
| 4 SD | Signal detect | Single-ended DCPECL logic output indicating optical signal presence (high = valid) |
| 5 VCCR | Receiver supply | +3.3 V input for Rx IC; requires local 0.1 μF + 10 μF decoupling near pin |
| 6 VCCT | Transmitter supply | +3.3 V input for Tx IC; separate filtering from VCCR minimizes crosstalk |
| 7 TD– | Transmitter data in (–) | LVPECL/LVDS differential input; internally AC-coupled and terminated |
| 8 TD+ | Transmitter data in (+) | Complementary differential input accepting 0.5–1.8 Vpp swing |
| 9 VEET | Transmitter ground | Direct connection to host board ground plane; isolated from VEER for EMI control |
Key Features
| Feature | Design Value |
|---|---|
| IEEE 802.3u 100BASE-FX compliance | Fully interoperable with standard Fast Ethernet PHYs without protocol translation or firmware |
| ACPECL input with integrated termination | Eliminates external 100 Ω resistors on TD+/TD– lines, reducing BOM count and layout area |
| DCPECL signal detect (SD) | Provides deterministic, hardware-based link status without microcontroller polling or software overhead |
| Wave-solder and aqueous-wash compatible | Enables high-yield, lead-free manufacturing without rework or optical subassembly damage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar optical transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-5813TQZ | Identical electrical/optical specs but uses ST duplex connector instead of SC | Requires ST-compatible patch panels and cables; incompatible with SC infrastructure | Select when legacy ST fiber plant is in place and connector interchangeability is not required |
| AFBR-5823QZ | 2×9 package with SFF-8472 DMI, Tx_Disable, SDA/SCL pins, and EEPROM diagnostics | Supports real-time monitoring (temperature, bias current, Rx power) and software-controlled shutdown | Choose only if digital diagnostics, remote fault isolation, or hot-plug management are mandatory system requirements |
Compared with AFBR-5813QZ, the AFBR-5813TQZ offers identical performance in an ST-connector form factor, while the AFBR-5823QZ adds digital monitoring at the cost of larger footprint, higher pin count, and increased firmware complexity - making AFBR-5813QZ optimal for cost-sensitive, analog-monitored 100BASE-FX deployments.

FAQ
Does AFBR-5813QZ support SFF-8472 digital diagnostics?
No, AFBR-5813QZ does not support SFF-8472. It is a 1×9 transceiver without DMI interface, EEPROM, or SDA/SCL pins. Digital monitoring features - including real-time temperature, bias current, and optical power reporting - are exclusive to the 2×9 AFBR-5823xxZ series. AFBR-5813QZ relies solely on analog signal detect (SD) and differential data I/O for status and communication.
What is the maximum supported fiber distance for AFBR-5813QZ?
AFBR-5813QZ supports up to 2 km over multimode fiber: specifically 62.5/125-μm (NA=0.275) or 50/125-μm (NA=0.2) fiber types. This distance is validated under IEEE 802.3u 100BASE-FX specifications with BER < 1×10⁻¹⁰, using the specified optical power budget (–20 dBm min launch, –31 dBm sensitivity) and modal bandwidth constraints.
Can AFBR-5813QZ be used in place of AFBR-5823QZ?
No, AFBR-5813QZ cannot replace AFBR-5823QZ in systems requiring SFF-8472 diagnostics, Tx_Disable control, or EEPROM-based configuration. The AFBR-5813QZ lacks pins 10, 17, and 18 (TX_Disable, SDA, SCL), has only 9 signal pins versus 20, and provides no digital interface. Mechanical fit and optical performance are similar, but functional substitution is not possible without hardware and firmware redesign.
What is the signal detect (SD) response time for AFBR-5813QZ?
The AFBR-5813QZ asserts SD within ≤100 μs after valid optical signal arrival (t_sd_on), and deasserts SD within ≤350 μs after optical loss (t_sd_off). This hardware-level timing is guaranteed across the full –40°C to +85°C operating range and requires no software polling - enabling immediate link-layer state transitions in Ethernet MACs or FDDI controllers.
Is AFBR-5813QZ RoHS compliant and certified for laser safety?
Yes, AFBR-5813QZ is RoHS I and II compliant per Directive 2011/65/EU and (EU) 2015-863, and certified as Laser Class 1 per EN 60825-1:Edition 3.0 (TÜV certificate R 50377267). Its 1300-nm InGaP LED emits non-hazardous optical radiation under all operating conditions, requiring no user-accessible safety interlocks or labeling beyond standard regulatory markings.
