GENERAL DESCRIPTION
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 offers programmable input equalization, loss-of-signal detection, programmable output swing, and output preemphasis/deemphasis.
