hi,

i have a problem of signal distortion as i think this is due to poor matching.this post is relevant my previous post



i need to know the techniques to matching these lines.(pixel clk,vref ,href) in the image i have attached the current setup.where i use two resistors as the voltage divider.

unfortunately i was unable to find the output impedance of the ov7620 cam module(not available on the datasheet).


please help me

thanks a lot!

Can you scope those pins and attach image here?
is those resistors are populated on the boards?
Please advise
 

The circuit would work much better with series resistor at the camera module and the divider at the receiver (FPGA) to my opinion.
