ADN4604: 4.25 Gbps 16 × 16 Digital Crosspoint Switch

The ADN4604 is a 16 × 16 asynchronous, protocol agnostic, digital crosspoint switch, with 16 differential PECL/CML-compatible inputs and 16 differential CML outputs.

The ADN4604 is optimized for NRZ signaling with data rates of up to 4.25 Gbps per port. Each port offers a fixed level of input equalization and programmable output swing and output pre-emphasis.

The ADN4604 non-blocking switch core implements a 16 × 16 crossbar and supports independent channel switching through the serial control interface. The ADN4604 has low latency and very low channel-to-channel skew.

An I²C or SPI interface is used to control the device and provide access to advanced features, such as additional levels of pre-emphasis and output disable.

The ADN4604 is packaged in a 16 mm × 16 mm, 100-lead TQFP package and operates from -40°C to +85°C.
