Hello,
I am very familiar with the all-in-one IR optical receiver, AGC, filters, and demodulator IC's such as a TSOP4838, etc.
What I am looking to do is basically a chip or circuit that will perform all of the above withouth the optical receiver. I have a wired modulated signal from a receiver at 12v pulled high, that I need to feed into a 5v input designed to take a demodulated 5v inverted signal (pulled-low).
I have experimented with using an inverting schmitt filter, which works fairly well; though, I am sure that if I were to actually provide gain and remove the carrier would work much better.
Does anybody have any suggestions, as far as circuits and / or chips.
By the way, this is my first post.
Thanks,
Gregory
