MC145157-2 - (MC145151-2 - MC145158-2) Parallel-Input PLL Frequency Synthesizer

Download the MC145157-2 datasheet PDF. This datasheet also covers the MC145151-2 variant, as both devices belong to the same (mc145151-2 - mc145158-2) parallel-input pll frequency synthesizer family and are provided as variant models within a single manufacturer datasheet.

General Description

INPUT PINS fin Frequency Input (Pin 1) Input to the ÷ N portion of the synthesizer.

fin is typically derived from loop VCO and is ac coupled into the device.

For larger amplitude signals (standard CMOS logic levels) dc coupling may be used.

RA2 Reference Address Inputs (Pins 5, 6, 7)

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145151–2/D 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.
