ML145152
Parallel-Input PLL
Frequency Synthesizer
Interfaces with Dual–Modulus Prescalers
Legacy Device: Motorola/Freescale MC145152
The ML145152 is programmed by sixteen parallel inputs
for the N and A counters and three input lines for the R
counter. The device features consist of a reference oscillator,
selectable–reference divider, two–output phase detector,
10–bit programmable divide–by–N counter, and 6–bit pro-
grammable ÷ A counter.
