The MAX96792A converts dual GMSL™ 3/2 serial inputs to MIPI CSI-2. It receives forward-channel video data, and simultaneously receives and transmits bidirectional control channel data over Coaxial or Shielded-Twisted Pair (STP) cables. The PAM-4 based GMSL3 serial link operates at 12Gbps in the forward direction and 187.5Mbps in reverse direction. The MAX96792A is backward compatible with GMSL2 and can be paired with 6Gbps or 3Gbps GMSL2 serializers. The GMSL inputs operate independently, allowing video with different timing and resolution to be received on each input. The two GMSL links can also have different data rates. Video data from both inputs can be aggregated for output on a single CSI-2 port and can be replicated on a second output port for redundant processing. The device is configured using an I²C or UART interface. GPIO, I²C, UART, and SPI tunnels are available.

The device is AEC-Q100 qualified.

Data can be transmitted over low-cost 50Ω Coax or 100Ω STP cables that meet the GMSL3 or GMSL2 channel specification. See Table 1 in data sheet for typical maximum cable lengths. Contact the factory for the GMSL3 or GMSL2 channel specifications.
