HMC778 Fractional-N PLL with Integrated VCO SMT, 9.6 - 10.8 GHz

VSAT Radio Microwave Point-To-Point Radios Test Equipment & Industrial Control Military End-Use Phased Array Applications FMCW Radar Systems

The HMC778LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) Frequency Synthesizer with an integrated Voltage Controlled Oscillator (VCO). The input reference frequency range is DC to 350 MHz while the advanced delta-sigma modulator design in the fractional synthesizer allows both ultra-fine step sizes and very low spurious products. The highly integrated structure provides excellent phase noise performance over temperature, shock and process. In addition, the HMC778LP6CE offers frequency sweep and modulation features, external triggering, double-buffering, exact frequency control, phase modulation and more. The HMC778LP6CE is packaged in a leadless QFN 6 x 6 mm surface mount package.

For theory of operation and register map refer to the "PLLs w/ Integrated VCO - Microwave VCOs" Operating Guide.
