Ethernet PHY Overview

Robust and reliable PHY's with industry's highest precision and lowest latency

EMI mitigation

Less noise emission/interference with other components on the board allows for more margin in system design.

Robust ESD performance

Built-in ESD allows for fewer external components and lowers costs for more robust and reliable systems.

Designed for low latency

Faster response time, greater predictability, and more nodes can be daisy-chained for more accurate and efficient systems.
