SIMPLE-TYPE CALLER ID FSK DECODER
12.15.1997
The input buffer accepts a differential AC coupled input signal through the TIP and RING input and feeds this
signal to a band pass filter. Once the signal is filtered, the FSK demodulator decodes the information and sents
it to a data valid energy detect circuit. The output data is then made available at DOUT pin. This data, as sent by
the central office, includes the header information (alternate “1” and “0”) and 150msec of marking which
precedes the date,time and calling number. If no data is present, the DOUT pin is held in a low state. This is
accomplished by an carrier detect circuit which determines if the in-band energy is high enough. If the incoming
signal is valid and thus the demodulated data is transferred to DOUT pin. If it is not, then the FSK demodulator
is blocked. This device uses a 3.58 MHz clok frequency driven from the external.
