KSZ8721B-TR Description

Short technical summary and product information.

The KSZ8721B-TR is a single-chip 100BaseTX/100BaseFX/10BaseT physical layer transceiver from Microchip Technology, operating at 2.5 volts to meet low voltage and low power requirements. It provides an MII to transmit and receive data, incorporating PMA, PMD, and PCS functions. The device 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 supports automatic configuration for 100 or 10 Mbps and full or half duplex operation through an on-chip Auto-Negotiation algorithm. It is fully compliant with the IEEE 802.3u standard and supports Media Independent Interface (MII) and Reduced MII (RMII). The KSZ8721B-TR includes features like power-down mode, power-saving mode, and configurable management ports.

 

Available in a 48-pin SSOP package, the KSZ8721B-TR is designed for 100BaseTX/10BaseT applications. It operates within a commercial temperature range of 0°C to +70°C. The device also supports MDI/MDI-X auto crossover and has 2.5V/3.3V tolerance on I/O pins.
