Hello, we are trying to make a FSK demodulator of intermediate frequency 500 kHz having mark frequency of 750 kHz and space frequency of 250 kHz.
We have tried using an LM 565 PLL to demodulate these modulation frequencies. When we tried the values we get for the sample circuit in the datasheet there were no results.
The demodulating circuits build using this component are usually operating at 2025 Hz - 2225 Hz.
Do you think these frequencies are too high to demodulate with this component? If this is not the case can you suggest any other component or schematics?
Thanks for the help in advance.
