Introduction
2 bit digital signal. In this mode, the KS8701 has a 8 receiver control lines used for warming up and shutting down
a receiver in stages. It also includes configuration setting for the two post detection filter bandwidths required to
decode the two symbol rates of the FLEX signal. Also when using an external demodulator, the oscillator
frequency (or external clock) must be 76.8 kHz and the CLKOUT signal (when enabled) is 38.4kHz clock output
capable of driving other devices.
