The AD8153 is an asynchronous, protocol agnostic, single-lane 2:1 switch with three differential PECL/CML-compatible inputs and three differential CML outputs. The AD8159, another member of the XstreamTM line of products, is suitable for similar applications that require more than one lane. The AD8153 is optimized for NRZ signaling with data rates of up to 3.2 Gbps per port. Each port offers two levels of input equalization and four levels of output pre-emphasis. The device consists of a 2:1 multiplexer and a 1:2 demultiplexer. There are three operating modes: pin mode, serial mode, and mixed mode. In pin mode, switching and equalization/preemphasis are controlled exclusively using external pins. In
