ADI HMC699LP5E

The HMC699LP5(E) is a frequency synthesizer with a wideband reversible polarity digital PFD and lock detect output. The divider operates from 160 - 7000 MHz with a continuous integer division ratio N = 56 to 519 and non-continuous division ratio N = 16 to 54. 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. For continuous division ratio, the A counter and S counter must satisfy the condition: A + 1 ≥ S.
