Product Summary

The KSZ8001 is a 10BASE-T/100BASE-TX/FX Physical Layer Transceiver, operating the core at 1.8 volts to meet low voltage and low power requirements. The solution provides MII/RMII/SMII interfaces to transmit and receive data. A unique mixed-signal design extends signaling distance while reducing power consumption. The KSZ8001 provides the most robust solution for eliminating the need to differentiate between crossover and straight-through cables.

Parametrics

KSZ8001 absolute maximum ratings: (1)Storage Temperature (TS): -55℃ to +150℃; (2)Supply Referenced to GND: -0.5V to +4.0V; (3)All pins: -0.5V to +4.0V.
