KSZ8051MLL Description

Short technical summary and product information.

The KSZ8051MLL from Microchip Technology is a single-supply 10Base-T/100Base-TX Ethernet physical layer transceiver designed for reliable data transmission over CAT-5 unshielded twisted pair cable. This highly integrated solution simplifies board layout with on-chip termination resistors and an integrated low-noise regulator for the 1.2V core.

 

Key features include MII interface support for direct connection with MAC processors and switches, MDC/MDIO management interface for PHY register configuration, and programmable interrupt outputs. It also offers diagnostic features like LinkMD TDR-based cable diagnostics and loopback modes for system bring-up and debugging. The transceiver supports auto-negotiation for automatic selection of the highest link speed and duplex mode.

 

This device is suitable for various applications including game consoles, IP phones, IP set-top boxes, IP TVs, LOM, and printers. It operates over a temperature range of 0°C to 70°C and is available in a compact 48-pin LQFP package, supporting surface mount installation. The voltage supply options include 1.8V, 2.5V, and 3.3V.
