Product details
Overview
ABCU-5741ARZ from Broadcom (formerly Avago Technologies) is a 10/100/1000BASE-T SFP electrical transceiver supporting full-duplex 1.25 Gb/s operation over Category 5 twisted-pair cable using 5-level PAM signaling. It features SGMII host interface, industrial temperature range (−40 °C to +85 °C), RX_LOS disabled, and integrated magnetics with custom RJ-45 connector - deployed in switch-to-switch Gigabit Ethernet links.
For engineers reviewing the ABCU-5741ARZ datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world use cases for SGMII-based embedded switches, and two confirmed alternative models with documented functional and interface differences.
Technical Context
The ABCU-5741ARZ implements a fully integrated SerDes/DSP PHY ASIC compliant with IEEE 802.3:2005 Clause 40 (1000BASE-T) and Clause 37 (1000BASE-X), supporting auto-negotiation across 10/100/1000 Mbps modes. Its SGMII interface operates at 1.25 Gb/s with AC-coupled differential TD+/RD± I/Os compatible with CML/LVPECL voltage swings.
It uses internal 100 Ω differential termination and on-module AC coupling, eliminating external capacitors on the host board. The RX_LOS pin is internally grounded via 100 Ω resistor (disabled per ordering code), and MOD-DEF0/1/2 enable serial ID EEPROM access per SFP MSA using 2-wire CMOS protocol.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 1.25 Gb/s - matches SGMII line rate; enables direct connection to MAC/SerDes without gearbox |
| Operating Temp | −40 °C to +85 °C - qualified for industrial-grade switch chassis and outdoor edge equipment |
| Supply Voltage | 3.3 V ±5% - single rail simplifies power design; VCCT and VCCR are separate pins for noise isolation |
| Power Dissipation | 1150 mW max - requires thermal management in dense SFP cages; inrush current ≤30 mA |
| Link Distance | Up to 100 m over Cat 5 - meets IEEE 802.3 standard; supports shielded and unshielded cabling |
| Interface Standard | SGMII - eliminates need for GMII/MII conversion logic; reduces host FPGA/ASIC pin count |
| Compliance | IEEE 802.3:2005, RoHS-6, FCC Part 15 Class B, CENELEC EN55022 Class B - certified for system-level EMI/EMC |
Pinout & Package
ABCU-5741ARZ uses the industry-standard 20-pin SFP pluggable module footprint (MSA-compliant), with metal housing and integrated RJ-45 jack/magnetics. Package dimensions conform to SFP MSA Rev 4.1 (13.4 mm × 56.5 mm × 8.5 mm).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 17, 20 | VEET | Transmitter ground - dedicated low-impedance return path for TD±; three pins reduce ground bounce |
| 3 | TX_DISABLE | Reset control input - high or open forces ASIC reset; pulled up internally with 4.7 kΩ |
| 4, 5 | MOD_DEF2 / MOD_DEF1 | 2-wire serial ID clock/data - connect to host I²C bus; require 4.7–10 kΩ pull-ups per MSA |
| 6 | MOD_DEF0 | Module presence detect - grounded internally via 100 Ω; signals hot-plug insertion to host |
| 8 | LOS | Loss of Signal - tied low (100 Ω to VEER); not used in RX_LOS-disabled variants like ABCU-5741ARZ |
| 9, 10, 11, 14 | VEER | Receiver ground - four dedicated returns for RD± integrity; decoupled separately from VEET |
| 12, 13 | RD− / RD+ | Differential receiver outputs - AC-coupled, 100 Ω terminated internally; swing 370–2000 mVdiff |
| 15 | VCCR | Receiver supply - 3.3 V ±5%; separate from transmitter rail to minimize crosstalk |
| 16 | VCCT | Transmitter supply - 3.3 V ±5%; filtered per MSA recommendations (1 μH + 0.1 μF) |
| 18, 19 | TD+ / TD− | Differential transmitter inputs - accept 500–2400 mVdiff; AC-coupled and 100 Ω terminated inside |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RJ-45 + magnetics | Eliminates external magnetics, PCB layout complexity, and BOM cost; supports both UTP and STP |
| SGMII host interface | Reduces MAC-to-PHY pin count by >70% vs. GMII; enables compact switch ASIC integration |
| Hot-pluggable SFP form factor | 3-stage pin sequencing (GND → VCC → signal) ensures safe insertion/removal under power |
| On-module SerDes/DSP | Performs full 1000BASE-T encoding/decoding, PAM-5 modulation, and echo cancellation internally |
| Industrial temperature rating | Validated operation from −40 °C to +85 °C - suitable for uncontrolled environments and extended thermal cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1000BASE-T SFP electrical transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABCU-5740ARZ | Same SGMII interface and industrial temp range, but RX_LOS enabled (pin 8 active high on link loss) | Required where host firmware monitors link status via LOS signal; incompatible if host expects grounded LOS | Select ABCU-5740ARZ only when explicit LOS reporting is needed; ABCU-5741ARZ avoids false alarms in noise-prone environments |
| AFBR-5710Z | Optical 850 nm SFP transceiver - requires fiber, no integrated magnetics, different power profile (3.3 V, ~350 mW) | Used for longer reach (>100 m), EMI-isolated, or fiber-only infrastructures; not drop-in electrically or mechanically identical | Choose AFBR-5710Z only when fiber cabling exists; ABCU-5741ARZ preserves copper infrastructure investment |
Compared with ABCU-5740ARZ, ABCU-5741ARZ removes LOS dependency for cleaner host interrupt handling; versus AFBR-5710Z, it retains copper compatibility and eliminates fiber alignment/maintenance overhead - making it optimal for retrofit and cost-sensitive industrial deployments.

FAQ
What is the operating temperature range of the ABCU-5741ARZ?
The ABCU-5741ARZ is rated for industrial temperature operation from −40 °C to +85 °C, verified per JEDEC JESD22-A108 and tested across full voltage and data-rate conditions. This range supports deployment in uncontrolled environments such as factory floors, outdoor cabinets, and vehicle-mounted networking gear - unlike commercial-grade variants (e.g., ABCU-5740RZ) limited to −5 °C to +70 °C.
Does the ABCU-5741ARZ support auto-negotiation with legacy 10/100BASE-T devices?
Yes, the ABCU-5741ARZ fully supports IEEE 802.3 Clause 28 auto-negotiation for 10/100/1000BASE-T modes. Its internal PHY advertises capabilities via registers 4 and 5, and negotiates speed/duplex with any standards-compliant endpoint - including older switches and NICs - without requiring host software intervention or manual configuration.
How is the RX_LOS function handled in the ABCU-5741ARZ?
In the ABCU-5741ARZ, RX_LOS is disabled per ordering code: pin 8 (LOS) is internally grounded via a 100 Ω resistor and provides no link-status indication. This differs from ABCU-5731ARZ (RX_LOS enabled), where pin 8 asserts high on loss of valid 1000BASE-T signal. Host designs must not monitor pin 8 for link state when using ABCU-5741ARZ.
What power supply filtering is required for the ABCU-5741ARZ?
The ABCU-5741ARZ requires MSA-compliant filtering on both VCCT and VCCR: a 1 μH inductor in series followed by parallel 0.1 μF and 10 μF capacitors per Figure 5. This suppresses switching noise and ensures PSNR ≥100 mV peak-peak over 10 Hz–2 MHz - critical for maintaining BER <10⁻¹² in noisy industrial power domains.
Is the ABCU-5741ARZ compatible with standard SFP host connectors?
Yes, the ABCU-5741ARZ complies fully with SFP MSA Rev 4.1 mechanical and electrical specifications. It mates with any MSA-compliant SFP cage and connector (e.g., TE Connectivity 1-1793270-1), supports hot-plug detection via MOD_DEF0 grounding, and sequences power/ground/signal pins correctly to prevent ESD damage during insertion.
