Introduction

AI Translation

KSZ9021GN is a fully integrated triple-speed Ethernet PHY transceiver supporting data transmission and reception over standard CAT-5 unshielded twisted-pair cable. The device provides an industry-standard GMII/MII interface for connecting to media access controllers in Gigabit Ethernet processors and switches, enabling data transfer at 1000 Mbps or 10/100 Mbps rates. It reduces board cost and simplifies layout by using on-chip termination resistors and an integrated LDO controller that drives a low-cost MOSFET to supply 1.2V core voltage. KSZ9021GN offers diagnostic features to facilitate system bring-up and debug during production testing and field deployment. Parametric and non-tree support enables fault detection between chip I/Os and the board. TDR-based cable diagnostics allow identification of faulty copper cables. Remote and local loopback functions provide verification of analog and digital data paths.
