HMC440QS16G

HMC440QS16G / 440QS16GE v03.0808 2.8 GHz INTEGER-N SYNTHESIZER (N = 2 - 32) INTEGER-N SYNTHESIZER - SMT Typical Applications The HMC440QS16G(E) is ideal for: Satellite Communication Systems Point-to-Point Radios Military Applications Sonet Clock Generation 8 Functional Diagram Features Ultra Low SSB Phase Noise Floor: -153 dBc/Hz @ 10 kHz offset @ 100 MHz Reference Frequency. Programmable Divider (N = 2 - 32) Operating up to 2.8 GHz Open Collector Output Buffer Amplifiers for Interfacing w/ Op-Amp Based Loop Filter QSOP16G SMT Package: 29.4 mm2 General Description The HMC440QS16G(E) is an Integer-n synthesizer that incorporates a 10 to 1300 MHz digital PhaseFrequency 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 offsetsynthesizer 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.
