MCHPKSZ9031RNXIC-TR
Overview
The KSZ9031RNXIC-TR is a highly integrated triple-speed 10/100/1000 Mbps Ethernet transceiver designed for RGMII interfaces. It features an integrated LDO controller and on-chip termination resistors to reduce BOM cost and simplify PCB layout in high-speed networking designs.
Why Choose This Part
This transceiver offers internal delay adjustments for the RGMII interface to simplify timing closure without requiring trace length matching on the PCB. It also includes comprehensive LinkMD cable diagnostics and a variety of power-saving modes, including Wake-On-LAN and energy-detect power-down.
Applications
Key Specifications
Getting Started
Designers should refer to the KSZ9031RNX evaluation board documentation to verify RGMII signal integrity and clocking requirements. Configuration is typically handled via the MDC/MDIO management interface to set parameters like internal delays and auto-negotiation.
