HMC839 Fractional-N PLL with Integrated VCO SMT, 1050 - 1205, 2100 - 2410, 4200 - 4820 MHz

The HMC839LP6CE 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 a triband 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 with Integrated VCO - RF VCOs" Operating Guide.
