+title: Maxim MAX9296A GMSL2 to CSI-2 Deserializer
+
+maintainers:
+ - Cosmin Tanislav <cosmin.tanislav@analog.com>
+
+description: >
+ The MAX9296A deserializer converts single or dual serial inputs to
+ MIPI CSI-2 outputs. The GMSL2 links operate at a fixed rate of 3Gbps
+ or 6Gbps in the forward direction and 187.5Mbps in the reverse
+ direction. In GMSL1 mode, each serial link can be paired with 3.12Gbps
+ or 1.5Gbps GMSL1 serializers or operate up to 4.5Gbps with GMSL2
+ serializers with GMSL1 backward compatibility. The MAX9296A supports
+ mixed GMSL2 and GMSL1 links. The serial inputs operate independently,
+ allowing videos with different timings and resolutions to be received
+ on each input.
+
+ MAX96716A supports both tunnel and pixel mode.
+
+ MAX96792A supports both tunnel and pixel mode, and has two GMSL3 links.
