Functional Diagram
General Description
The HMC439QS16G is a digital phase-frequency
detector intended for use in low noise phase-
locked loop applications for inputs from 10 to
1300 MHz. Its combination of high frequency
of operation along with its ultra low phase noise
鏗俹or make possible synthesizers with wide loop
bandwidth and low N resulting in fast switching
and very low phase noise. When used in
conjunction with a differential loop ampli鏗乪r, the
HMC439QS16G generates an output voltage that
can be used to phase lock a VCO to a reference
oscillator. The device is packaged in a low cost,
surface mount 16 lead QSOP package with an
exposed base for improved RF and thermal
performance.
