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.
