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
performanceI

Description
DC power input: +12 V to + 24 V
Electrical and mechanical ground
Note: I = input, O = output, I/O = bi-directional signal, P = power/ground, NC = not connected
6.2 Command and Control
The CameraLink 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.

CC1 - Synchronization input
Note: I = input, O = output, I/O = bi-directional signal, P = power/ground, NC = not connected
The TTL/I/O interface provides two TTL signals dedicated to camera control.

Description
ODD-D[11-0]
O
RS644
Odd pixel data, ODD-00 = LSB, ODD-11 = MSB
EVEN-D[11-0]
O
RS644
Even pixel data, EVEN-00 = LSB, EVEN-11 = MSB
STROBE
O
RS644
Output data clock, data valid on the rising edge
LVAL
O
RS644
Line valid or line enable, active high signal
FVAL
O
RS644
Frame valid or frame enable, active high signal
Note:
1. I = input, O = output, I/O = bi-directional signal, P = power/ground, NC = not connected
2. Note: DVAL, as defined in the CameraLink standard, is not used. DVAL is permanently tied to
1 (high) level.
