BCM5488SA7KPBG

The Broadcom BCM5488SA7KPBG is an octal-port, fully integrated 10/100/1000BASE-T Gigabit Ethernet transceiver. It provides eight complete transceivers in a single 484-pin PBGA package, enabling high port density for networking switches and infrastructure equipment. The device supports SGMII and SerDes MAC interfaces, and is fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards. It operates at data rates of 10 Mbps, 100 Mbps, and 1 Gbps in both full and half duplex modes. Key design features include jumbo frame support up to 10 KB, IEEE 1149.1 and 1149.6 JTAG boundary scan, and trace-matched output impedance. The transceiver is fabricated in 0.13-micron CMOS technology, delivering typical power consumption of less than 625 mW per port, with advanced power management capabilities. It also includes CableChecker diagnostics for cable plant characterization and automatic MDI/MDIX crossover. The device is packaged in a 484-BGA (supplier device package 484-PBGA) and is surface mount compatible. This product is intended for last time buy status and is available in tray packaging.

Designed for high-density Ethernet applications, the BCM5488SA7KPBG reduces system BOM cost by lowering PCB layer requirements and minimizing I/O pin count. The transceiver supports line side copper or 100BASE-FX fiber mode, and offers robust cable-sourced electrostatic discharge (CESD) tolerance exceeding 3 kV.
