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.

Evaluation Kits (1)
The ADN4612 evaluation board user guide describes the setup and general usage of the ADN4612 evaluation board. Included in this document is a quick start guide, hardware configuration instructions, and software installation instructions.
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.
The evaluation board example is shown fully populated with SMA connectors. The board is shipped with only eight installed SMA connectors. The SMA connectors can be moved to any of the 48 locations on the board by unscrewing and then reattaching the connectors to the desired locations. The customer can purchase an additional 40 SMA connectors from several different sources and attach the connectors for a fully populated board. The Bill of Materials section in this user guide provides the SMA connector part number, which is Molex 73251-1851 or equivalent.
All microstrip (top layer) transmission lines use an 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.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
