ML12179
500-2800 MHz Single Channel
Frequency Synthesizer
Legacy Device: Motorola MC12179
The ML12179 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 ML12179 serves as a
complete PLL subsystem. 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 Current
• 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 TA = –40° to +85°C
