The MC12179 is a monolithic Bipolar synthesizer integrating the high frequency prescaler, phase/frequency detector, charge pump, and reference oscillator/buffer functions. When combined with an external loop filter and VCO, the MC12179 serves as a complete PLL subsystem. Motorola's advanced MOSAICTM V technology is utilized for low power operation at a 5.0 V supply voltage. The device is designed for operation up to 2.8 GHz for high frequency applications such as CATV down converters and satellite receiver tuners.
