11.3 Gbps 12 × 12 Digital Crosspoint Switch
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.
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.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Each input and output pair is ac coupled using a 0.1uF capacitor. All microstrip (top layer) transmission lines use RoHS compliant, Rodgers 4003 dielectric. The differential transmission line pairs are 15.5 mils wide with 30+ mil spacing and are designed to have a differential characteristic impedance of 100Ω’s. The strip line (middle layers ) transmission lines are RoHS compliant FR-4 material.
Three variants of the evaluation board allow access to specific I/Os.
