BCM5221A4KPTG Description

Short technical summary and product information.

The BCM5221A4KPTG is a 10/100BASE-TX/FX Mini-Φ transceiver from Broadcom Limited. It integrates a single driver/receiver pair and supports both MII and RMII interfaces for flexible connectivity. The device operates from a supply voltage of 2.5V to 3.3V and includes an integrated voltage regulator for single-supply operation. Power consumption is under 175 mW, aided by intelligent power management and energy detection circuits.

 

This transceiver is designed for Fast Ethernet applications and features DSP-based Signi-PHY architecture for robust performance across temperature, voltage, and process variations. It supports IEEE 1149.1 JTAG scan chain for testing and includes HP Auto-MDIX for automatic cable detection. Cable diagnostic features provide remote monitoring of cabling infrastructure.

 

The part is offered in a 64-pin TQFP surface-mount package (inferred) and is rated for industrial temperature operation from -40°C to 85°C. It is RoHS3 compliant (unverified) and suitable for embedded 10/100BASE-TX applications including LAN on motherboard, IP phones, and network controllers.
