概述

Description

BCM54285C1KFBG is a Broadcom Gigabit Ethernet PHY (physical layer transceiver). It provides a single-port 10/100/1000BASE-T interface to connect a MAC to copper Ethernet cables. Key capabilities typically include auto-negotiation for speed/duplex, support for 10/100/1000BASE-T operation, and standard PHY management via MDIO with interfaces to the MAC such as MII/RMI/MMII/GMI/GMII/RGMII depending on implementation. It’s used in embedded NICs, switches, routers, and other networking equipment where a MAC-to-copper PHY is needed. The suffix C1KFBG denotes the RoHS-compliant, lead-free packaging variant and Broadcom’s specific revision/packaging for this part. As with most PHYs, it requires a MAC and a management interface to configure and monitor status.

Features

BCM54285C1KFBG is a Broadcom Gigabit Ethernet controller with the following features:
- 1-port 10/100/1000BASE-T MAC/PHY
- PCIe host interface
- Fully integrated MAC and PHY (no external PHY needed)
- Auto-negotiation, full/half duplex, and flow control
- Jumbo frames support (up to ~9K)
- VLAN offload and 802.1Q support
- Hardware multicast filtering
- Checksum offload (IPv4/IPv6, TCP/UDP) and Large/Receive Offload (LSO/LRO)
- Receive-side scaling and high-performance DMA engine
- Wake-on-LAN (WOL)
- Energy Efficient Ethernet (EEE)
- MSI/MSI‑X interrupts with optional interrupt moderation
- Low power/power management for embedded/server use
(Compatibility and exact options vary by implementation; verify specific datasheet for your SKU.)
