+title: Samsung S5K3T2 Image Sensor
+
+description:
+  Samsung S5K3T2 (ISOCELL 3T2) image sensor is a 20MP image sensor.
+  The sensor is controlled over a serial camera control bus protocol,
+  the widest supported output image frame size is 5184x3880 at 15 frames
+  per second, data output format is RAW10 transferred over 4-lane
+  MIPI D-PHY interface.
