FRACTIONAL-N PLL WITH INTEGRATED VCO
1050 -1205, 2100 - 2410, 4200 - 4820 MHz
General Description
The HMC839LP6CE 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 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 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 fas-
ter 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”. To

Number” pull down menu.
