KSZ8721BI Description

Short technical summary and product information.

The Microchip Technology KSZ8721BI is a single-chip 10BaseT/100BaseTX/FX Physical Layer Transceiver designed for low voltage and low power requirements, operating at 2.5 volts. It provides an MII to transmit and receive data, incorporating PMA, PMD, and PCS functions.

 

This transceiver fully complies with the IEEE 802.3u standard and supports both MII and Reduced MII (RMII) interfaces. It offers auto-negotiation for 10/100Mbps speed and full/half-duplex operation. The KSZ8721BI includes on-chip filtering for 10BaseT and 100BaseTX, eliminating the need for external filters and allowing a single set of line magnetics.

 

Key features include support for Far_End_Fault Detection, power-down and power-saving modes, and configurable management ports. It also provides LED outputs for link, activity, duplex, collision, and speed status. The device is available in a 48-pin SSOP package and operates within a commercial temperature range of 0°C to +70°C or an industrial range of -40°C to +85°C.

 

With its integrated analog front-end filtering and support for MDI/MDI-X auto crossover, the KSZ8721BI is an ideal choice for 100BaseTX/10BaseT applications requiring a compact and efficient physical layer solution.
