In GMSL2 mode, the MAX9295D operates at a fixed rate of 3Gbps or 6Gbps in the forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the MAX9295D can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1 deserializers or operate up to 4.5Gbps with GMSL2 deserializers configured for GMSL1 mode. Operation is specified over the automotive temperature range of -40°C to +105°C and the device is AEC-Q100 Grade 2 qualified. Cable can be coaxial or shielded twisted pair (STP).
