12MHz Sine to Square IC?
12MHz Sine to Square IC?
(OP)
Hi everyone,
I have a 12MHz, 0.8Vpp clip sine wave coming from a VCO and I need to square up this signal to TTL-compatible logic. The TI's CDC3RL02 can do the conversion, but its output is only 1.8V. I will need another level converter to convert it to 3.3V.
Is there any IC out there that can convert 0.8V clip sine wave to 3.3V square wave?
Regards,
James

How is the output jitter with a comparator? What's the advantage of an open collector output?

Other possibilities:
An alternative would be an op-amp to increase the voltage followed by a Schmidt trigger.
Use a dual op-amp and use the first one as an amp and the second one as a comparator.
