HMC836LP6CE
FRACTIONAL-N SYNTHESIZER WITH
INTEGRATED VCO, 3365 - 3705 MHz
General Description
The HMC836LP6CE 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 x2
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 HMC836LP6CE from the “Search by Part Number”
