概述

Description

BCM84846A1KFSBLG is a Broadcom high‑speed SerDes PHY (front-end transceiver) used to implement the physical layer in networking equipment. It provides one or more high‑speed SerDes lanes with PMA/PCS functionality for links such as Ethernet and similar interfaces, typically on network switches, routers, NICs, or line cards. The A1 denotes a device revision, and KFSBLG encodes the packaging/lead‑free variant in Broadcom’s naming convention. This part is intended to be used on the host PCB with other PHY/PHY‑to‑MAC logic and external serializer/deserializer connections. For exact specifications (lane count, supported speeds, power, interfaces, and pinout), refer to the official BCM84846 data sheet and product brief on Broadcom’s website.

Features

Here are the typical features of Broadcom BCM84846A1KFSBLG (Quad 10/100/1000BASE-T PHY):
- Four independent 10/100/1000BASE-T PHY interfaces
- Auto-Negotiation and auto-MDIX on each port
- IEEE 802.3 compliant PHY with 10/100/1000BASE-T support
- Management via MDIO/MDC interface for register access
- PCS/PMA sublayers with per-port speed/duplex handling
- MAC-side interfaces (commonly SGMI/RGMII options) to connect to a MAC/switch
- Per-port LED drivers and status/control features
- Cable diagnostics, link status monitoring, and diagnostic/test modes (e.g., loopback)
- Energy Efficient Ethernet (IEEE 802.3az) and low-power operation
- Packaging: Broadcom A1KFSBLG (BGA) with industrial/extended temperature suitability
- Applications: NICs, switches, network appliances requiring four 1G PHYs
Note: exact MAC interface options and temperature range are device-specific; consult the datasheet for precise electrical characteristics and supported interfaces.
