KSZ8051RNL Description

Short technical summary and product information.

The KSZ8051RNL from Micrel Inc. is a single-chip, AEC-Q100 qualified Ethernet physical layer transceiver designed for automotive applications. It complies with the 10Base-T/100Base-TX IEEE 802.3 standards, providing reliable network connectivity.

 

This transceiver supports the RMII v1.2 interface, requiring a 50 MHz reference clock. It includes features such as MDC/MDIO management for PHY register configuration, programmable interrupt outputs, and LED indicators for link, activity, and speed status. The device also incorporates on-chip termination resistors for differential pairs and supports HP Auto MDI/MDI-X for automatic cable connection detection and correction.

 

Designed for in-vehicle networking, the KSZ8051RNL operates on a single 3.3V power supply, with options for VDD I/O at 1.8V, 2.5V, or 3.3V. It features a built-in 1.2V regulator for the core. The device is available in a compact 32-pin 5 mm x 5 mm QFN package, suitable for space-constrained automotive electronic systems.
