I have a ZCU102 DemoBoard, an FMC-CameraLink board from AlphaData that converts SDR connector to FMC and a Tamarisk 640 camera.
From the datasheet of the camera, LVDS interface has 2.5V output with VOHmin = 2.1V @ IOH = -1mA and VOLmax = 0.4V @ IOL = -1mA.
SDRtoFMC board converter uses LA_xx FMC pins that are identified as LVCMOS18 on ZCU102 User Guide (UG1182) (they are an HP I/O).
Can I connect camera to SDR-FMC board and than to ZCU102?

Do you have a link to that data sheet? The Camera Link spec. uses standard LVDS signalling, which should have a common mode voltage of around 1.2V and no more than 400 mV of swing into 100 Ohm differential termination. The VOHmin and VOLmax values you posted look like they are related to a single-ended LVCMOS output rather than LVDS. The manual I found on the web says:
"This configuration provides digital outputs in the form of 8-bit or 14-bit parallel digital video (LVCMOS UART), 8-bit or 14-bit Camera Link® video"
I'm wondering if you got your spec from the parallel digital version?

It still doesn't look right. If it's not a typo (possibly left over from the parallel version) then it's not really Camera Link compliant. I would contact the manufacturer to see if this is really a typo or if they are using unusual voltage levels on their "Camera Link" interface.

If it's worth anything, the CameraLink output on this camera does work through the frame grabbers I've used. You'll get CameraLink and/or parallel data (Two different video channels).
