PLLs with integrated VCO - sMt
2
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.
