产品概览
The KSZ8081RNBIA is a single-port 10/100 Ethernet PHY transceiver from Microchip with RMII v1.2 MAC interface. It integrates on-chip termination resistors, a 1.2V core regulator, and HP Auto-MDIX for automatic crossover cable detection. The industrial-grade (-40 to +85C) variant is in a 32-pin QFN (5x5mm) package with EtherCAT support.
