Functional Diagram
General Description
The HMC439QS16G & HMC439QS16GE are digital
phase-frequency detectors 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
floor 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 amplifier, the HMC439QS16G &
HMC439QS16GE generate output voltages 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.
