Overview
The AD8153ACPZ from Analog Devices Inc. is a high-speed, asynchronous, protocol-agnostic switch designed for serial link applications. It features a 2:1 multiplexer and a 1:2 demultiplexer with three differential CML (Current Mode Logic) inputs and three differential CML outputs. This device is optimized for NRZ (Non-Return-to-Zero) signaling with data rates up to 3.2 Gbps per port, making it suitable for high-speed data transmission and redundancy in serial links.
