CSI-2 to GMSL2 Serializer

The MAX96717R GMSL™ serializer receives video on a 4-lane MIPI CSI-2 interface and outputs it on a GMSL2 serial link transceiver for transport over a coaxial cable. Simultaneously, it sends and receives bidirectional control channel data across the same GMSL2 link. The GMSL2link operates at a fixed rate of 3Gbps in the forward direction and 187.5Mbps in the reverse direction. The device is programmed through a local I2C interface or across the link from a matching deserializer. The MAX96717Rfeatures flexible GPIO tunnels and register-programmed GPIO. Operation is specified over the automotive temperature range of -40°C to +105°C. The device is AEC-Q100grade 2 qualified.

Data can be transported over low-cost 50Ω coax cables that meet the GMSL2 channel specification. Table 1 provides guidance to typical maximum lengths of commonly used automotive cables. Contact the factory for the GMSL2 Channel Specification.
