Serial-Input PLL Frequency
Synthesizer
Interfaces with Single–Modulus Prescalers
stream. The device features consist of a reference oscillator, selectable–refer-
ence divider, digital–phase detector, 14–bit programmable divide–by–N
counter, and the necessary shift register and latch circuitry for accepting serial
input data.
MC145155–1. Power consumption has decreased and ESD and latch–up
performance have improved.
