APPLICATION NOTE
For fractional multipliers with more than one digit,
HCC/HCF4527B devices may be cascated in two
differentmodes: the Addmode andtheMltiplymode
(see figures 1 and 2).
When two units are cascated in Add mode and pro-
grammed to 9 and 4 respectively, the more signifi-
cantunitwill have 9 output pulses for every 10 input
pulses and the other unit will have 4 output pulses
for every 100 input pulses for a totalof:

In the multiply mode, the fraction programmed into
the first rate multiplier is multiplied by the fraction
programmed into the secondone:
