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