Functional Diagram
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.
