+title: GMSL2 to CSI-2 Serializer

+
+description: |
+  The MAX96717F serializer converts MIPI CSI-2 D-PHY or C-PHY formatted input
+  into GMSL2 serial outputs. The device allows the GMSL2 link to
+  simultaneously transmit bidirectional control-channel data while forward
+  video transmissions are in progress. The MAX96717F can connect to one
+  remotely located deserializer using industry-standard coax or STP
+  interconnects. The device cans operate in pixel or tunnel mode. In pixel mode
+  the MAX96717F can select the MIPI datatype, while the tunnel mode forward all the MIPI
+  data received by the serializer.
+  The MAX96717F supports Reference Over Reverse (channel),
+  to generate a clock output for the sensor from the GMSL reverse channel.
+
+  The GMSL2 serial link operates at a fixed rate of 3Gbps in the
+  forward direction and 187.5Mbps in the reverse direction.

+      The MAX96717F will pass through and forward the I2C requests from the
+      incoming GMSL2 link. Therefore it supports an i2c-gate
+      subnode to configure a sensor.
