General Description

the hMC769LP6Ce 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 hMC769LP6Ce offers frequency sweep and modulation features, external

triggering, double-buffering, exact frequency control, phase modulation and more. the hMC769LP6Ce 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.

Number” pull down menu.
