Functional Diagram
General Description
The HMC440QS16G integrates a 10 to 1300 MHz
digital Phase-Frequency Detector with a 10 to 2800
MHz 5-Bit Counter (continuous division from 2 to 32)
in a miniature 16 lead QSOP plastic package. It is
intended for use in low phase noise offset-synthesizer
applications. The HMC440QS16G鈥檚 combination of
high frequency operation along with ultra low phase
noise 鏗俹or make possible synthesizers with wide
loop bandwidth and low N resulting in fast settling
and very low phase noise. When used in conjunction
with a differential loop ampli鏗乪r, the HMC440QS16G
generates an output voltage that can be used to
phase lock a VCO to a reference oscillator.
