SEMICONDUCTOR TECHNICAL DATA
Serial-Input PLL Frequency
Synthesizer
Interfaces with Dual–Modulus Prescalers
stream. The device features consist of a reference oscillator, selectable–refer-
ence divider, digital–phase detector, 10–bit programmable divide–by–N
counter, 7–bit programmable divide–by–A counter, and the necessary shift
register and latch circuitry for accepting serial input data.
MC145156–1. Power consumption has decreased and ESD and latch–up
performance have improved.
