1. General Description

The LT8644 is a 16×16 digital crosspoint switch, with 16 differential CML compatible inputs and 16 differential CML outputs. The LT8644 is optimized for nonreturn-to-zero (NRZ) signaling with data rates of up to 3.4 Gbps per port. Each port offers programmable level of input equalization and programmable output swing. The LT8644 supports independent channel switching through the serial control interface. The LT8644 has low latency and very low channel-to-channel skew. An I2C interface is used to control the device and provide access to advanced features.
