TVP5150 Video Decoder

Other Parts Discussed in Thread: TVP5150, TVP5150AM1

I am using TVP5150 Video decorder for receiving CVBS Camera input.

I used to make a digital output receives a CVBS Camera input of D1 level.

But video output qulity is very low.

So, I would like to know how can I improve video quailty.

I guess that needs to adjust filter of TVP5150.

Thank you for advice.

    Looking at your schematic it looks like you have an error in your analog input circuit.

    Please refer to figure 6-1 in the TVP5150AM1 datasheet. You will see that the input signal level needs to be divided by 2 using 2x 37.4R resistors in series rather than a single 75R termination resistor.

    As a test try replacing L401 and R401 with 37.4R resistors.
