FUNCTIONAL DESCRIPTION
Figure 6 is shown functional blocks of W91031. The device must operate with a 3.579545 MHz
system clock and consists four major functions and decribed as follows:
Ring Detector
The application circuit in Figure 7-1 illustrates the relationship between the RNGDI, RNGRC and
RNGON signals. The three pin combination is used to detect an increase of the RNGDI voltage from
ground to a level above the Schmitt trigger high going threshold voltage V
