PLL Frequency Synthesizer Family - CMOS
The devices described in this document are typically used as low–power, phase–locked loop frequency
synthesizers. When combined with an external low–pass filter and voltage–controlled oscillator, these
devices can provide all the remaining functions for a PLL frequency synthesizer operating up to the
device's frequency limit. For higher VCO frequency operation, a down mixer or a prescaler can be used
between the VCO and the synthesizer IC.
These frequency synthesizer chips can be found in the following and other applications:
CATV
TV Tuning
AM/FM Radios
Scanning Receivers
Two–Way Radios
Amateur Radio
OSC ÷R
CONTROL LOGIC

Parallel-Input PLL
Frequency Synthesizer
Interfaces with Single–Modulus Prescalers
Legacy Device: Motorola/Freescale MC145151
The ML145151 is programmed by 14 parallel–input data
lines for the N counter and three input lines for the R counter.
The device features consist of a reference oscillator, selec-
table–reference divider, digital–phase detector, and 14–bit
programmable divide–by–N counter.
