The HMC699LP5(E) is a frequency synthesizer with a wideband reversible polarity digital PFD and lock detect output. The divider operates unconditionally from 160 - 7000 MHz with a continuous integer division ratio of 56 to 519. The HMC699LP5(E) 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 filter, the HMC699LP5(E) can be used to phase lock a VCO to a reference oscillator.
