Description
AI
The HMC840LP6CE 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.APPLICATIONSCellular/4G InfrastructureRepeaters & FemtocellsCommunications Test EquipmentCATV EquipmentPhased Array ApplicationsDDS ReplacementVery High Data Rate Radios
