AC101LIQTG

Overview

The AC101LIQTG is a single-port 10/100BASE-TX Ethernet transceiver manufactured by Broadcom Limited. It integrates a PHY layer for Fast Ethernet applications, supporting both 10 Mbps and 100 Mbps data rates over twisted-pair cabling. The device features Auto-MDIX capability to automatically detect cable type, eliminating the need for crossover cables. It utilizes an RMII (Reduced Media Independent Interface) or MII interface for connection to a host MAC controller. The component is designed for low power consumption and is housed in a compact LQFP package suitable for embedded networking solutions.

Feature Summary

• Integrated 10/100BASE-TX PHY with Auto-MDIX support
• RMII/MII digital interface for host connectivity
• Ultra-low-power architecture for energy efficiency

Applications

• Embedded industrial networking equipment
• Smart home IoT gateways and routers
• Consumer electronics with Ethernet connectivity

Procurement Notes

Verify the exact suffix 'L' and 'IQTG' against official Broadcom documentation to confirm temperature range and packaging specifications. Ensure compatibility with the target system's voltage levels and clock requirements before integration. Check for end-of-life status or alternative recommendations from the manufacturer.

Selection Notes

Select this component when a cost-effective, low-pin-count solution for 10/100 Mbps Ethernet is required. Confirm that the host processor supports the RMII or MII interface standard. Evaluate power budget constraints as the device is optimized for low-power operation compared to higher-speed alternatives.
