Hi guys.
I am doing a project where i want to use FSK modulator and demodulator connected to microcontrolers (pic) for a radio link.
I have XR 2206/XR 2211 and the LM567 tone decoder. They work but they are old chips, some versions even obsolete, and i would prefer to give a more modern look to the project. I've tried to look around for modern replacement's but no luck.
Cristal controlled oscillators would be better for lower frequency drift versus temperature. Also if the frequency could be higher (at least 1Mhz) even better.
Any ideias?
Tks
