Description
The AD8155 is an asynchronous, protocol-agnostic, dual-lane 2:1 switch with a total of six differential CML inputs and six differential CML outputs. The signal path supports NRZ signaling with data rates up to 6.5 Gbps per lane. Each lane offers programmable receive equalization, programmable output preemphasis, programmable output levels, and loss-of signal detection.
