Hi.
Well I'm contemplating what type of sync separator to construct.
I have a 74LS123 in stock and am going to give that a whirl. The LM1881 is another dedicated sync separator but more designed for 525/625 and higher line & field rates, I'm not too sure if it would cope with lower line and frame rates or mechanical systems.
I'm also in the process of building a 555 sawtooth generator but again unsure about whether I can sync it up OK.
So far I've had good success down to 96/25p with a synced up function generator.
Lower mechanical systems I believe use the audio output from the Multistandard Aurora for sync if I'm not mistaken.
Perhaps Jeffrey can help here.
