HMC439QS16GE Datasheet PDF - ADI

●The HMC439QS16GE is a SMT digital Phase-frequency Detector intended for use in low noise phase-locked loop applications for inputs from 10 to 1300MHz. 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(E) generate output voltages that can be used to phase lock a VCO to a reference oscillator. The device with an exposed base for improved RF and thermal performance.

● Ultra low SSB phase noise floor

● Differential input/single ended output

● Open collector output buffer amplifiers
