500-2800 MHz Single Channel
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.
• 2.8 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°C
For additional information on calculating the loop filter components, an
InterActiveApNote™ document containing software (based on a Microsoft
Excel spreadsheet) and an Application Note is available. Please order
DK306/D from the Motorola Literature Distribution Center.
