+title: Sony IMX662 CMOS Image Sensor
+
+description:
+  The Sony IMX662 is a 1/2.8-inch CMOS image sensor with a pixel
+  array of 1936x1100 pixels, capable of 1920x1080 resolution at up
+  to 90 fps. It supports MIPI CSI-2 output with 2 or 4 data lanes,
+  RAW10/RAW12 output, and both colour and monochrome variants.
