KSZ8721CL-TR Description

Short technical summary and product information.

The KSZ8721CL-TR is a single-chip 10/100BASE-TX/FX physical layer transceiver from Microchip Technology, designed for Fast Ethernet applications. It provides MII/RMII interfaces to MACs and switches, supporting 10BASE-T, 100BASE-TX, and 100BASE-FX standards.

 

This transceiver operates on a single 3.3V power supply with a power consumption of less than 340mW. It features an on-chip auto-negotiation algorithm for automatic configuration of 10/100Mbps speed and full-/half-duplex modes. The device includes on-chip analog front-end filtering for both 100BASE-TX and 10BASE-T, eliminating the need for external filters.

 

The KSZ8721CL-TR is available in a 48-LQFP package suitable for surface mounting. It operates within a commercial temperature range of 0°C to 70°C. The transceiver supports power-down and power-saving modes, and includes LED outputs for link, activity, duplex, and speed status.
