Zero crossing detector.

Ciao,
I need infos about a zero crossing detector circuit that give me a pulse on each
halfwave transition of the AC line. I'm working around a PWM circuit controlled
by a BS2, and all that I need is a zero crossing pulse (TTL level, not for a
triac driving).
Thanks for every help.
Alberto.
