General Description
The HMC698LP5(E) is a frequency synthesizer with
a wideband reversible polarity digital PFD and lock
detect output. The divider operates unconditionally
from 80 - 7000 MHz with a continuous integer division
ratio of 12 to 259. The HMC698LP5(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 HMC698LP5(E) can be used to phase
lock a VCO to a reference oscillator.
