Legacy Device: Motorola/Freescale MC145151
lines for the N counter and three input lines for the R counter.
The device features consist of a reference oscillator, selec-
table–reference divider, digital–phase detector, and 14–bit
programmable divide–by–N counter.
The ML145151 is programmed by 14 parallel–input data
