Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Serial-Input PLL Frequency Synthesizer with Analog Phase Detector Interfaces with Dual–Modulus Prescalers The MC145159–1 has a programmable 14–bit reference counter, as well as fully programmable divide–by–N/divide–by–A counters.
The counters are programmed serially through a common data input and latched into the appropriate counter latch, according to the last data bit (control bit) entered.
When combined with a loop filter and VCO, this device can provide all the remaining functions for a PLL frequency synthesizer operating up to the device’s frequency limit.
For higher VCO frequency operations, a down mixer or a dual–modulus prescaler can be used between the VCO and the PLL.
