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.
