Hi,
I've been looking at some old designs and am wondering if the SAA1101 is
still the best option, or has it been superseded by something better?
TIA

Hopefully pertinent questions:
1:Is this to run composite or component?
2:Is the video mono or color?
3:Is the genlock timing important?
If you're running composite, a sync generator is a big can of worms.
Subcarrier and its phasing relative to sync is a headache.
Component/mono will be easier. Monostables are terrible devices in a
sync generator just as its mechanical equivalent, the hourglass, is a
lousy clock. The adjustable timing maybe needed for genlock seems OK
for a monostable but I promise, you'll find it too unstable. Counters
off the master clock are good but use a lot of devices (in the TTL
world).
Since you don't like the idea of register loading or microcontrollers,
you might be better off checking used broadcast equipment. A 20 year
old Lietch or Tektronix would do just fine. Add up the parts and your
time and the used unit looks pretty good.
