KSZ8721BT Description

Short technical summary and product information.

The KSZ8721BT from Microchip Technology is a single-chip 10/100BaseTX/FX physical layer transceiver designed for low voltage and low power applications. Operating at 2.5V, it meets stringent power requirements with consumption under 200mW. This device provides an MII to transmit and receive data, incorporating PMA, PMD, and PCS functions. It features on-chip filtering for both 100BaseTX and 10BaseT, eliminating the need for external filters and allowing a single set of line magnetics.

 

This transceiver fully complies with the IEEE 802.3u standard and supports both MII and Reduced MII (RMII) interfaces. It automatically configures for 100 or 10 Mbps and full or half duplex operation through an on-chip Auto-Negotiation algorithm. Additional features include support for power-down and power-saving modes, configurable management ports, LED outputs for link status, activity, duplex, collision, and speed, as well as MDI/MDI-X auto crossover.

 

The KSZ8721BT is available in a 48-pin TQFP package suitable for surface mounting. It operates within a commercial temperature range of 0°C to 70°C and has 2.5V/3.3V tolerance on its I/O pins.
