The ADN4612 is a 12 × 12 asynchronous, protocol agnostic, digital crosspoint switch with 12 differential PECL-/CML-compatible inputs and 12 differential CML outputs.

The ADN4612 is optimized for nonreturn-to-zero (NRZ) signaling with data rates of up to 11.3 Gbps per port. Each port provides programmable input equalization, loss of signal (LOS) detection, programmable output swing, and output preemphasis/deemphasis.

The ADN4612 nonblocking switch core implements a 12 × 12 crossbar and supports independent channel switching through the serial control interface. The ADN4612 has low latency and very low channel-to-channel skew.

The ADN4612 is packaged in an 88-lead LFCSP package and operates from -40°C to +85°C.
