Overview
The AD8159ASVZ is a high-performance, asynchronous, protocol-agnostic quad-lane 2:1 switch and 1:2 demultiplexer integrated circuit manufactured by Analog Devices Inc. This device is optimized for NRZ signaling with data rates of up to 3.2 Gbps per lane, making it suitable for high-speed serial link applications. It features 12 differential PECL-/CML-compatible inputs and 12 differential CML outputs, and each lane operates independently with low latency and minimal lane-to-lane skew.
