General Description
11
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.
