Sinewave to square wave conversion

Stand alone Hi-speed dual channel Comparator modules from Pulse Research Lab detect sinewave and small signals (as small as 10 mV) and convert them to logic-level outputs. PRL offers models with complementary ECL, PECL, LVPECL, or TTL outputs. An RS-422 output versions is also available on special order. The PRL-255CN is a frequency divider (f/2 and /f4) with the same input circuit as the PRL-350 Series, and can divide sinewaves or small-amplitude signals.

Please see our Sinewave Conversion FAQ for other models that can convert sinewaves (200 mV min amplitude)
