v02.1109
FRACTIONAL-N SYNTHESIZER WITH
INTEGRATED VCO, 1815 - 2010 MHz
General Description
The HMC831LP6CE 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, an
autocalibration subsystem for low voltage VCO tuning, a very low noise digital Phase Detector (PD), a precision cont-
rolled 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 HMC831LP6CE from the “Search by Part Number”
pull down menu.

The circuit board used in the final application should use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground leads and exposed paddle should be connected
directly to the ground plane similar to that shown. A sufficient number of via holes should be used to con-
nect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon
request.
