Quad Tunneling GMSL2/1 to CSI-2 Deserializer

The MAX96724/F/R deserializer converts four GMSL™2/1 inputs to 1, 2, or 4 MIPI D-PHY or C-PHY outputs. The device allows simultaneous transmit bidirectional transmissions over 50Ω coax or 100Ω STP cables that meet the GMSL channel specification. Contact the factory for the GMSL supporting collateral.

Up to four remotely located sensors can be supported using industry-standard coax or STP interconnects. Each GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the forward direction and 187.5Mbps in the reverse direction. The MAX96724/F/R supports both aggregation and replication of video data, enabling streams from multiple remotely located sensors to be combined and routed to one or more of the available CSI-2 outputs.
