Hi Team,

As I mentioned is previous thread, our customer would like to use THS7372 for the application below:

Please help to check if this schematic available or not:

1. FHD1/IN and FHD2/IN are connected in same source.

2. "RCAM_OUT" and "CVBS OUT+" are connected together to CVBS/out.

3. Please help to check if any issue of impedance matching

4. unused pin connection.

5. Any others

Thank you very much!

Best regards,

C.T.

Hi C.T.

The termination looks good, but I am a little confused by the naming. If CVBSOUT+ and RCAM_OUT are connected, then it looks like pins 1, 14, 9, and 10 are shorted together. Is that correct?

Hi C.T.

For the CVBS out channel, are both outputs being terminated to another 75 Ohms (150 Ohms total on each output)? If that is the case it will load the output slightly more than typical with just one connection and may cause some performance degradation.
