 13description: |
 14  The MAX96712 deserializer converts GMSL2 or GMSL1 serial inputs into MIPI
 15  CSI-2 D-PHY or C-PHY formatted outputs. The device allows each link to
 16  simultaneously transmit bidirectional control-channel data while forward
 17  video transmissions are in progress. The MAX96712 can accommodate as many as
 18  four remotely located sensors using industry-standard coax or STP
 19  interconnects.
 20
 21  Each GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the
 22  forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the
 23  MAX96712 can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1
 24  serializers or operate up to 3.12Gbps with GMSL2 serializers in GMSL1 mode.
