Objective: I'm trying to make a wired infrared input for a microcontroller. Incoming signal would come from a remote control device that has an IR emitter output jack.
I believe that all I need is the demodulator and perhaps schmitt trigger portion since the incoming signal will be well controlled and will not contain IR noise or variations in level.
notes: I've found a few older ICs that were designed for use with a separate diode and seem that they could fit the bill but are not available any more. I also found a Vishay line of apparently current devices (VSOP584) that could work but are very tiny and I'm not sure that I could fab one up in a way that would survive. I have to think that a relatively easy to build circuit could demodulate the signal since it's wired and doesn't suffer most of the issues that a real IR input would have.
I think I have 3 options:
A) use an ir emitter coupled to an ir receiver inside my device.
B) keep searching for an IC that will do the demodulation.
C) design a demodulator (perhaps try with a basic envelope detector).
Any suggestions on which option I should take?
