Frequency Synthesizer

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 MOSAIC

™ 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.

– 2.0 to 11 MHz Operation When Driven From Reference Source

– 5.0 to 11 MHz Operation When Used With a Crystal

For additional information on calculating the loop filter components, an

InterActiveApNote
