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.
2.8 GHz Maximum Operating Frequency
Low Power Supply Current of 3.5 mA Typical, Including ICC
and IP Currents
Supply Voltage of 5.0 V Typical
Integrated Divide by 256 Prescaler
On–Chip Reference Oscillator/Buffer
– 2.0 to 11 MHz Operation When Driven From Reference Source
– 5.0 to 11 MHz Operation When Used With a Crystal
Digital Phase/Frequency Detector with Linear Transfer Function
Balanced Charge Pump Output
Space Efficient 8–Lead SOIC
Operating Temperature Range of –40 to 85
