PLL Frequency Synthesizers
(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
AM/FM Radios
Two-Way Radios
TV Tuning
Scanning Receivers

MC145151-2 Parallel-Input (Interfaces with Single-Modulus Prescalers)
1 MC145151-2 Parallel-Input (Interfaces with
Single-Modulus Prescalers)
The MC145151-2 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, selectable-reference divider,
digital-phase detector, and 14-bit programmable divide-by-N counter.
The MC145151-2 is an improved-performance drop-in replacement for the MC145151-1. The power
consumption has decreased and ESD and latch-up performance have improved.
1.1 Features
• Operating Temperature Range: - 40 to 85°C
• Low Power Consumption Through Use of CMOS Technology
• 3.0 to 9.0 V Supply Range
• On- or Off-Chip Reference Oscillator Operation
• Lock Detect Signal
÷ N Counter Output Available
• Single Modulus/Parallel Programming
• 8 User-Selectable ÷ R Values: 8, 128, 256, 512, 1024, 2048, 2410, 8192
÷ N Range = 3 to 16383
• “Linearized” Digital Phase Detector Enhances Transfer Function Linearity
• Two Error Signal Options: Single-Ended (Three-State) or Double-Ended
• Chip Complexity: 8000 FETs or 2000 Equivalent Gates
