General Description

the HMc839lp6ce is a fully functioned Fractional-n phase-locked-loop (pll) with an integrated voltage controlled oscillator (vco). the pll consists of an integrated low noise vco with a tri-band output, an autocalibration subsystem for low voltage vco tuning, a very low noise digital phase detector (pd), a precision controlled charge pump, a low noise reference path divider and a fractional divider.
