BCM54385C1KPBG

The BCM54385C1KPBG is a high-performance, energy-efficient Quad-Port Gigabit Ethernet (GbE) transceiver from Broadcom (now part of Avago). It integrates four 10/100/1000BASE-T PHYs with advanced power management, supporting IEEE 802.3az (Energy-Efficient Ethernet).
Key features:
- 4x GbE ports with auto-negotiation and auto-MDI/MDIX.
- Supports RGMII, SGMII, and SerDes interfaces for flexible connectivity.
- Low power consumption with EEE and Wake-on-LAN (WoL) support.
- Compliant with IEEE 802.3, 802.3u, 802.3ab, and 802.3az standards.
- Industrial temperature range (-40°C to +85°C) for rugged applications.
Commonly used in switches, routers, NAS, and embedded networking systems. The BGA package (19x19mm) ensures compact integration.
