[Preliminary] ATMOS -2M60/2M30
6. Electrical Interface
6.1
Power Supply
It is recommended to insert a 1A fuse between the power supply and the camera. The voltage
ripple of the power supply shall be below 50 mVp-p at BW = 50 MHz to have full camera
performance.

Command and Control
The Camera Link interface provides four LVDS signals dedicated to camera control (CC1 to
CC4). On the ATMOS, one of them is used to synchronize the camera on external events.
