Product Details

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.

EVAL-ADN4612 Circuit Diagram

Product Details

The ADN4612 evaluation board provides access to all 12 differential input ports and 12 differential output ports of the ADN4612 via top launch SMA connectors. Each input and output pair is ac-coupled using a 0.1 μF capacitor.

All microstrip (top layer) transmission lines use a RoHs compliant, Megtron-6 dielectric. The differential transmission line pairs are 10 mil wide with 7.5 mil spacing and are designed to have a differential characteristic impedance of 100 Ω. The stripline (middle layers) transmission lines are RoHs compliant, FR-4 material.
