HMC831LP6CE
FRACTIONAL-N PLL WITH
INTEGRATED VCO, 1815 - 2010 MHz
General Description
The HMC831LP6CE 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, 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 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”.

Note 1: This maximum phase detector frequency can only be achieved if the minimum N value is respected. eg. In the case of fractional feedback
mode, the maximum PFD rate = fvco/20 or 100 MHz, whichever is less.
