BCM5488SA7KPBG

Drivers, Receivers, Transceivers Overview

The BCM5488SA7KPBG is an octal-port Gigabit Ethernet transceiver manufactured by Broadcom Limited. It integrates eight fully independent 10/100/1000BASE-T transceivers on a single monolithic chip using a 0.13-micron CMOS process. The device supports SGMII and SerDes MAC interfaces, reducing pin counts significantly compared to standard GMII. It operates with power consumption of less than 625 mW per port and provides over 3 kV of cable-sourced electrostatic discharge (CESD) tolerance. The component utilizes a 484-pin PBGA package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A7K' against official datasheets to confirm temperature range and packaging variations. Confirm current lifecycle status as distributors may list this part as discontinued or end-of-life. Ensure compatibility with existing PCB footprints for the 484-pin PBGA package before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple Gigabit ports within a constrained footprint. The integrated DSP architecture and advanced power management make it suitable for environments where thermal constraints are critical. Verify that the host MAC supports the required SGMII or SerDes interface protocols.

Drivers, Receivers, Transceivers Part Context

This component belongs to Broadcom’s 0.13-µm Gigabit Ethernet copper PHY family. It is designed to lower system BOM costs by eliminating PCB layers needed for routing high-density solutions. The device maintains industry-leading margins over IEEE requirements for echo and crosstalk.

Drivers, Receivers, Transceivers Replacement Considerations

Check for EOL notifications from Broadcom. Potential substitutes include other octal-port PHYs from the same manufacturer family, such as the BCM54881B1KFBG, provided interface and pinout compatibility is verified.
