HMC836LP6CE
v07.1211
FRACTIONAL-N PLL WITH
INTEGRATED VCO, 3365 - 3705 MHz
General Description
The HMC836LP6CE 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 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 PLL features an advanced delta-sigma modulator design that allows both 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”.
