The synthesizer consists of an integrated low noise VCO with divideby-2 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 w/ Integrated VCOs - RF VCOs" Operating Guide. To view the Operating Guide, please visit www.hittite.com and choose HMC824LP6CE from the "Search by Part Number" pull down menu.
