calculate loop freqn for demodulator using ne564 pll.

[K.ganesh]

Dear friends,

I am using ne/se564 philips ic as a demodulator.
the free running centre freqn is 20 khz. the freqn for mark and space
will be 15khz and 25 khz. the modulating freqn will be around 1500 hz.

pls help me to calculate the capacitor values for lock freqn and
capture freqn as I am not able to understand from the datasheets
provided by the philips semiconductor site.

thanks and regards
