ML145156
Serial–Input PLL
Frequency Synthesizer
Interfaces with Dual–Modulus Prescalers
Legacy Device: Motorola/Freescale MC145156-2
The ML145156 is programmed by a clocked, serial input,
19–bit data stream. The device features consist of a reference
oscillator, selectable–reference divider, digital–phase detector,
10–bit programmable divide–by–N counter, 7–bit program-
mable divide–by–A counter, and the necessary shift register
and latch circuitry for accepting serial input data.
