Base Camera Link SDR Connector


1378

Table 2. Signal Descriptions
Signal Name Description
X<3..0>± Base configuration data and enable signals from the camera to the NI PCIe-1437
XCLK± Transmission clock on the Base configuration chip for Camera Link communication between the NI PCIe-1437 and the camera
SerTC± Serial transmission to the camera from the NI PCIe-1437
SerTFG± Serial transmission to the NI PCIe-1437 from the camera
CC<4..1>± Four LVDS pairs, defined as camera inputs and NI PCIe-1437 outputs, reserved for camera control. On some cameras, the camera controls allow the NI PCIe-1437 to control exposure time and frame rate
