Ulf,

What level of jitter would you consider acceptable?

Try PL133-37, I am using it for sinewave shaping on some of designs - including my 30ps pulser.

Gentlemen,
I have so far been using LT1016 as a pulse shaper and also whenever I needed toconvert a sine wave into TTL Logic levels. Some hysteresis and all the decouplingand layout precautions as recommended by LT.
Are there any similar or better alternatives out there that could be usedthat would provide lower jitter and that are less expenceive?

Somewhat worse than an LTC6957 particularly at low offset frequencies.

Either that or the manufacturers PN noise measurement method doesn't work well at low offsets.
