Dual GMSL2 to CSI-2 Deserializer

The MAX96716F converts dual GMSL2 serial inputs to MIPI CSI-2. It also transmits and receives control channel data, enabling transmission of forward-path video and bidirectional control data. The GMSL2 link operates at a fixed rate of 3Gbps in the forward direction and 187.5Mbps in the reverse direction.

The GMSL™ inputs operate independently, allowing video with different timing and resolution to be received on each input.

Video data from both inputs can be aggregated for output on a single CSI-2 port or replicated on a second port for redundant processing.

The device and connected serializer are programmed through I2C or UART.

Operation is specified over the automotive temperature range of -40°C to +105°C and the device is AEC-Q100 qualified.

Data may be transmitted over low-cost 50Ω Coax or 100Ω STP cables that meet the GMSL2 channel specification. Contact the factory for the GMSL2 channel specification.
