Product details
Overview
ABCU-5730ARZ 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 integrates SerDes, DSP, and magnetics in an industry-standard SFP form factor, operates from a single +3.3 V supply, and features RX_LOS indication with industrial temperature range (–40 °C to +85 °C). It enables direct copper interconnects in switch-to-switch and backplane applications.
For engineers reviewing the ABCU-5730ARZ datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions, real-world use cases, and validated alternative parts - all grounded in the official ABCU-57xxxxZ family datasheet and MSA-compliant specifications.
Technical Context
The ABCU-5730ARZ implements IEEE 802.3:2005-compliant 1000BASE-T physical layer functionality with integrated auto-negotiation (Clause 28), 5-level PAM encoding/decoding, and embedded magnetics within a custom RJ-45 connector. Its internal ASIC supports register-level control via I²C-compatible 2-wire serial interface (MOD_DEF1/MOD_DEF2) and exposes standard SFP control signals including TX_DISABLE and RX_LOS.
It uses ac-coupled differential SerDes I/O (TD±, RD±) with internal 100 Ω termination and supports CML/LVPECL voltage swing compatibility. The module performs hot-plug detection via 3-stage pin sequencing (ground → power → signal) and includes EEPROM-based serial ID per SFP MSA for host identification and configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 1.25 Gb/s - matches Gigabit Ethernet line rate; enables 1000 Mbps full-duplex throughput over CAT5 |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial environments without derating |
| Supply Voltage | +3.3 V ±5% - single rail simplifies power design; VCCT and VCCR are separate pins but share same nominal voltage |
| Power Dissipation | 1150 mW max - defines thermal management requirements on host board |
| Link Distance | Up to 100 m - compliant with IEEE 802.3 clause 40 for 1000BASE-T over unshielded/shielded CAT5 |
| RX_LOS Function | Link-up/link-down indicator - not AC-coupled loss-of-signal detector; asserted high when link is down |
| Interface Standard | SFP MSA-compliant 20-pin edge connector - ensures mechanical and electrical interoperability with standard SFP cages |
Pinout & Package
ABCU-5730ARZ uses the industry-standard Small Form Pluggable (SFP) package (13.4 mm × 56.5 mm × 8.5 mm) with 20-pin card-edge connector per SFP MSA. Pin assignment follows Figure 2 of the datasheet and Table 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 17, 20 | VEET | Transmitter ground reference - three dedicated pins reduce ground impedance and improve EMI performance |
| 9, 10, 11, 14 | VEER | Receiver ground reference - four pins ensure stable return path for high-speed RD± signals |
| 15 | VCCR | Receiver power supply - +3.3 V ±5%; supplies analog/digital receiver circuitry |
| 16 | VCCT | Transmitter power supply - +3.3 V ±5%; powers transmitter driver and magnetics interface |
| 12, 13 | RD−, RD+ | Differential receiver outputs - ac-coupled, internally terminated 100 Ω; compatible with CML/LVPECL SerDes inputs |
| 18, 19 | TD+, TD− | Differential transmitter inputs - ac-coupled, 100 Ω internally terminated; accepts 500–1200 mV diff swing for optimal EMI |
| 3 | TX_DISABLE | Transmitter reset control - pulled up internally; low = active transmit, high/open = reset state |
| 8 | LOS | Loss-of-signal indicator - high = link down; only enabled on ABCU-573xxxZ variants like ABCU-5730ARZ |
| 4, 5 | MOD_DEF2, MOD_DEF1 | I²C serial ID clock/data - used for EEPROM read/write; require 4.7–10 kΩ pull-up on host board |
| 6 | MOD_DEF0 | Module presence detect - tied to ground via 100 Ω resistor; signals module insertion to host |
Key Features
| Feature | Design Value |
|---|---|

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 | No RX_LOS output - LOS pin grounded internally; identical electrical specs, temperature range, and pinout | Preferred where link-status monitoring is handled externally or not required | Select ABCU-5740ARZ if RX_LOS signal is unnecessary; otherwise ABCU-5730ARZ provides native link-up/down visibility. |
| AFBR-5710Z | Optical SFP (850 nm VCSEL); requires fiber instead of copper; higher power (1300 mW), different eye diagram compliance | Used for longer reach (>100 m), EMI-isolated, or legacy fiber plant integration | Choose AFBR-5710Z only when fiber infrastructure exists; ABCU-5730ARZ avoids fiber cost, transceivers, and patch panels for copper-dominant deployments. |
Compared with ABCU-5740ARZ, ABCU-5730ARZ adds actionable link-status feedback without changing layout or power design; versus AFBR-5710Z, it delivers lower system cost and simpler deployment for sub-100 m copper links - making it optimal for cost-sensitive, space-constrained industrial and enterprise edge applications.

FAQ
What is the operating temperature range of the ABCU-5730ARZ?
The ABCU-5730ARZ is rated for industrial temperature operation from –40 °C to +85 °C, as confirmed in the "Recommended Operating Conditions" table of the datasheet. This range applies to case temperature (TC) and is validated across all electrical parameters including supply current, power dissipation, and signal integrity - making ABCU-5730ARZ suitable for deployment in uncontrolled environments such as factory floors or outdoor enclosures without additional thermal mitigation.
Does the ABCU-5730ARZ support auto-negotiation?
Yes, the ABCU-5730ARZ fully supports IEEE 802.3:2005 auto-negotiation per Clause 28 (twisted-pair) and Clause 37 (1000BASE-X). It advertises 10/100/1000BASE-T capabilities and negotiates speed, duplex mode, and PAUSE flow control with the link partner. Auto-negotiation is enabled by default and can be disabled or restarted via internal ASIC register 0 (Control Register) bit 0.12 and bit 0.9 respectively - all accessible through the MOD_DEF1/MOD_DEF2 I²C interface.
What is the function of the LOS pin on the ABCU-5730ARZ?
On the ABCU-5730ARZ, the LOS (pin 8) functions as a link-up/link-down indicator - not a traditional AC-coupled loss-of-signal detector. It asserts high when the 1000BASE-T link is down and de-asserts low when link is established. This behavior is specific to ABCU-573xxxZ models and differs from optical SFPs; the datasheet explicitly states that for ABCU-5730ARZ, RX_LOS reflects link status rather than signal amplitude threshold crossing.
Can the ABCU-5730ARZ be used with SGMII host interfaces?
No - the ABCU-5730ARZ is designed for standard SerDes interfaces compliant with SFP MSA electrical specifications (CML/LVPECL), not SGMII. Models with "SGMII" in the part number (e.g., ABCU-5731ARZ) include modified internal register mapping and timing to support SGMII protocol framing. Using ABCU-5730ARZ with an SGMII host will result in link failure due to incompatible control signaling and lack of SGMII-specific auto-negotiation extensions.
Is an external EEPROM required for ABCU-5730ARZ operation?
No - the ABCU-5730ARZ includes an integrated 2-wire serial EEPROM (AT24C01A-compatible) that stores SFP MSA-compliant serial ID data, including vendor name, part number, date code, and compliance information. Host systems read this memory via MOD_DEF1 (clock) and MOD_DEF2 (data) pins; no external EEPROM is needed for basic operation or identification. The module's internal ASIC uses this memory for plug-and-play recognition and configuration validation.
