Ethernet PHY Enhances Power and ESD Rating

Micrel’s KSZ8041NL is a single-supply 10Base-T/100Base-TX Ethernet PHY, which provides Media Independent Interface (MII) and Reduced MII interfaces to transmit and receive data.

The KSZ8041NL Fast Ethernet transceiver combines low power consumption of 150mWand ESD ratings of 6kV, exceeding ESD requirements formost industrial applications.

The mixed-signal design extends signalling distance while reducing power consumption. By implementing HP Auto-MDI/MDI-X, the PHY also provides a highly robust solution for eliminating the need to differentiate between crossover and straight-through cables.

This combination of features means that the chip is ideal for applications where PCB space is at a premium, where low power is important, and where stringent ESD conditions apply such as in industrial Ethernet environments.

This sixth-generation low-cost, low-power PHY comes in a 5mm x 5mm QFN package. With a small footprint and low bill-of-materials cost, the KSZ8041NL supports the rapid and seamless spread of Ethernet connectivity.
