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. 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 MC145151-2 MC145152-2 MC145155-2 MC145156-2 MC145157-2 MC1 [ ... ]
