FRACTIONAL-N SYNTHESIZER w/ INTEGRATED VCO
1095 - 1275, 2190 - 2550, 4380 - 5100 MHz
General Description
The HMC820LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) Frequency Synthesizer with an
Integrated Voltage Controlled Oscillator (VCO). The synthesizer 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 synthesizer 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 w/ Integrated VCOs - RF VCOs” Operating Guide. To view
the Operating Guide, please visit www.hittite.com and choose HMC820LP6CE from the “Search by Part Number”
pull down menu.
