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.

Features

1. Dual 2:1 mux/1:2 demux
2. Optimized for dc to 6.5 Gbps NRZ data
3. Per-lane P/N pair inversion for routing ease
4. Loss-of-signal detection
5. Programmable output preemphasis up to 12 dB
6. Programmable output levels with squelch and disable
7. Accepts ac-coupled or dc-coupled differential CML inputs
8.  1.8 V to 3.3 V flexible core supply
9. Low power, typically 2.0 W in basic configuration

Applications : 

1. Low cost redundancy switch
2. SONET OC48/SDH16 and lower data rates
3. RXAUI, 4× Fibre Channel, Infiniband, and GbE over backplane
4. OIF CEI 6.25 Gbps over backplane
5. Serial data-level shift
