KSZ8851-32MQLI

Featuring analog circuitry for improved signal transmission and reception efficiency, the KSZ8851 is designed using a low-power CMOS process with flexible power supply options. This single chip device supports management information base (MIB) counters and CPU control/data interfaces with single shared data bus timing, ensuring seamless integration within embedded systems. Furthermore, the inclusion of cable diagnostics feature called LinkMD® and support for HP Auto-MDIX simplifies cabling and connectivity challenges in diverse applications
