BCM53134OKFBG Description

The BCM53134OKFBG is a low-power integrated Gigabit Ethernet switch IC from Broadcom. It integrates Gigabit Ethernet PHYs, MACs, switch fabric, buffers, VLAN, QoS, and rate control in a single 256-ball FBGA package. It is designed for home gateways, SOHO/SMB routers, and other networked devices requiring compact size and reduced power consumption.

BCM53134OKFBG Features

Ultra-low power consumption for green networking designs

4 × 10/100/1000BASE-T PHYs and 2 additional ports for CPU or uplink connections

Non-blocking switch fabric with integrated packet buffers

Advanced QoS with per-port scheduling, SP, WRR, and WDRR

VLAN and access list support for secure traffic segmentation

Sleep and idle modes for further power savings

256-ball FBGA package (11 × 11 mm) for compact design

Fully compliant with IEEE 802.3/802.3x standards

BCM53134OKFBG Applications

BCM53134OKFBG Manufacturer

Broadcom Limited was a leading global designer, developer, and supplier of a wide range of semiconductor and infrastructure software solutions. The company was originally formed after Avago Technologies acquired Broadcom Corporation in 2016, adopting the Broadcom name. Headquartered in San Jose, California, Broadcom combined Avago’s expertise in wired infrastructure, wireless communications, enterprise storage, and industrial markets with Broadcom’s strengths in networking, broadband, and wireless connectivity. Its product portfolio included Ethernet switches, network processors, storage controllers, RF components, optoelectronics, and broadband access solutions. Broadcom Limited played a key role in enabling fast, reliable, and secure connectivity across data centers, enterprise networks, cloud infrastructure, and consumer electronics.

BCM53134OKFBG FAQs
