TFP410: CameraLink connector and DVI transmitter

Marcus Ritter

Part Number: TFP410
Other Parts Discussed in Thread: DS90CR288A

Hello, I am planning to connect a camera with a cameralink interface to an FPGA Evolution board with an FMC connector and display the camera image on a monitor. I will design an FMC board for this and I have some questions for this.

1) Do TFP410 data pins need to be connected to FPGA or Camera

2) Is Level Translator required?

3) How to connect cameralink connector to fmc connector? Is there a pin table?

4) CameraLink Connector - DS90CR288A - TFP410 - DVI Connector is valid scheme? What pins should I connect from camlink connector to DS90CR288A? or how could I connect?

Thank you.

Best Regards.

I'm not super familiar with the two interfaces, but this looks like a prebuilt solution: https://www.alpha-data.com/product/fmc-cameralink/

This depends of which parts you use. Ideally try to get a system that works off of the same common mode voltage and output swing.

This depends on where the TFP410 goes. I'm assuming the DVI cable will be commented to the monitor and the RGB values will come from the FPGA?

The TFP410 is an RGB to LVDS converter, but the DS90CR288A is a LVCMOSTTL to LVDS converter. This makes the above signal chain incompatible. I am not familiar with any reference designs that may help. This is a product I found online, they may be able to help. https://www.daqsystem.com:8006/eng/page/product/emb-dvi01.html

thank you for your response.

I found this block diagram is this correct?

if DS90CR288A is incompatible then should I directly connect from cameralink to fmc connector?

also, you are right about my first question's answer but i just want to display camera image to 1920x1080 @60hz monitor which tfp410 is support this specification. so in this situation TFP410 data - pins should connect to fpga (FMC connector) ?

Thank you.

Hey Marcus,

Sorry but I'm still not sure I fully understand the system you're looking to design, Would this block diagram be an accurate representation of your system?

yes, it would be an accurate representation. in this case, should I connect TFP410's DATA pins to FPGA ?
