HMC439QS16G

FREQUENCY DIVIDERS & DETECTORS - SMT HMC439QS16G / 439QS16GE v02.0705 HBT DIGITAL PHASE-FREQUENCY DETECTOR, 10 - 1300 MHz 6 Typical Applications This Phase Frequency Detector is a key component in low phase noise frequency synthesis applications such as: Point-to-Point Radios Satellite Communication Systems Military Applications Sonet Clock Generation Features Ultra Low SSB Phase Noise Floor: -153 dBc/Hz @ 10 kHz offset @ 100 MHz Input up to 1300 MHz Fin. Differential Input/Single Ended Output Open Collector Output Buffer Amplifiers QSOP16G SMT Package: 29.4 mm2 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.
