Sync processor / cleanup

Post by g8gtz » Tue Jun 10, 2014 11:57 am

Hi

Does any have a circuit to clean up analogue syncs for use on noisy ATV signals?

If so would appreciate a circuit, preferably in time to let me build before the contest next weekend!

Hi Noel,

We use a MAX7450 video signal conditioner ic on GB3GV, G8OBP built the circuit, so don't know where he the found info.

Did a quick Google CQTV 222 page 19 for a start, lots of references on the web.

Not many connections once you have the chip, possibly, getting rather old now?

Nothing using discreet components though comes to mind.

Weekend looks good!

Hi Noel,

Right under our nose, as it were.

Thanks Peter for all the help - I ordered a couple from RS and found Dave's site earlier.

Running out of time for the weekend though.
