FRACTIONAL-N PLLs w/ INTEGRATED VCO
1095 - 1275, 2190 - 2550, 4380 - 5100 MHz
General Description
The HMC820LP6CE 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.
The fractional PLL features an advanced delta-sigma modulator design that allows both ultra-fine step sizes and low
spurious products. The phase detector (PD) features cycle slip prevention (CSP) technology to allow faster frequency
hopping times. Ultra low in-close phase noise and low spurious also allows wider loop bandwidths for faster frequency
hopping and low micro-phonics.
For theory of operation and register map refer to the “PLLs
with Integrated VCOs - RF VCOs Operating Guide”.

view the Operating Guide, please visit www.hittite.com and choose HMC820LP6CE from the “Search by Part
Number” pull down menu.
