Overview

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145149/D MC145149 Dual PLL Frequency Synthesizer Interfaces with Dual–Modulus Prescalers The MC145149 contains two PLL Frequency Synthesizers which share a common serial data port and common reference oscillator.
The device contains two 14–stage R counters, two 10–stage N counters, and two 7–stage A counters.
All six counters are fully programmable through a serial port.
The divide ratios are latched into the appropriate counter latch according to the last data bits (control bits) entered.
When combined with external low–pass filters and voltage controlled oscillators (VCOs), the MC145149 can provide all the remaining function...
