FSK Reference Voltage Output
This pin usually keeps open.
This fixed output voltage may be
available for the FSK reference
voltage of wave shaping comparator
by connecting to pin7. This usage
is effective in shaping the data
signal with continuous bits of the
same polarity, and discussed in
another document related to
applications information.
IF Output
An external phase - shifting
capacitor is connected between
pin9 and pin10.
Quadrature Detector Input
An external phase - shifting coil or
ceramic discriminator is connected.
FM Demodulated Signal Output
An external 3rd order multiple feed
- back filter (RC filter) is connected
between pin11 and pin13.
