Functional Diagram
General Description
The HMC440QS16G(E) is an Integer-n synthesizer
that incorporates a 10 to 1300 MHz digital Phase-
Frequency Detector with 10 to 2800 MHz 5-Bit
Frequency Counter (continuous division from 2 to
32) in miniature 16 lead QSOP plastic packages.
It is intended for use in low phase noise offset-
synthesizer applications. The HMC440QS16G(E)’s
combination of high frequency operation along
with ultra low phase noise floor 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
amplifier, the HMC440QS16G(E) generates an
output voltage that can be used to phase lock a VCO
to a reference oscillator.
