ISCAS-89 s208.1 Frequency Divider
Statistics: 10 inputs; 1 output; 112 gates;
Function: The functional model for the s208.1 frequency divider (also called a fractional multiplier) is shown in above. The control lines C determine if the P input pulse train is passed to the output Z, or if a frequency-divided version is passed. For every N input pulses on P, there are N*C/256 pulses on Z. If C equals 256, all pulses on P are passed to Z.
