The BCM5248UA4KQMG is an eight-port Fast Ethernet transceiver IC from Broadcom, built to handle the physical-layer work behind 10/100 Mbps networking equipment. Design engineers and repair teams reach for this part when a multi-port switch, media converter, or legacy networking board needs a proven PHY that keeps running for years without issue.

Broadcom built this device as part of its OCTAL-Φ transceiver line, a family aimed at dense, multi-port Ethernet switching. It ships in a 128-pin QFP package suited to standard SMD assembly.

Here is what makes it a solid choice for network hardware production and repair work:

BCM5248UA4KQMG

Key Features of the BCM5248UA4KQMG

Eight independent Fast Ethernet PHY channels

One chip handles the 10BASE-T and 100BASE-TX/FX physical-layer work for eight separate ports, cutting board space and part count in multi-port switch designs.

HP Auto-MDIX support

Each port automatically detects and corrects cable wiring, so straight-through and crossover cables work without manual configuration or extra adapters.

CableChecker diagnostics

Built-in diagnostics flag shorts, opens, and cable length on each link, giving technicians a way to troubleshoot cable runs without separate test gear.

SMII/SSSMII switch interface

A low-pin-count serial connection links the device to a switch controller, simplifying board layout compared with standard MII wiring.

128-pin QFP package for SMD assembly

The part runs on a 1.8V core with 2.5V/3.3V I/O at roughly 200 mW per port, keeping the thermal load manageable on dense switchboards.

RoHS-compliant, Pb-free construction

Built to current environmental compliance standards, the BCM5248UA4KQMG is well-suited to OEM and EMS production lines that require RoHS-certified components.

Applications of the BCM5248UA4KQMG

This part is typically used in:

  • Managed and unmanaged Fast Ethernet LAN switches
  • SOHO and consumer-grade network switches
  • Industrial Ethernet switches for factory automation
  • Telecom access and central office equipment
  • Network interface cards and Ethernet expansion cards
  • Copper-to-fiber media converters
  • Blade server and chassis networking modules
  • VoIP infrastructure and PBX systems
  • Legacy network equipment repair and sustainment
  • Data center access-layer switching hardware
