Fractional-N PLL frequency synthesizer integrates a low-noise voltage controlled oscillator with tri-band RF outputs from 1.31 GHz to 5.66 GHz. The device supports 24-bit frequency step control with typical 3 Hz resolution, exact frequency mode, digital self test, and a serial CMOS control interface. Typical in-band phase noise is -110 dBc/Hz, and the figure of merit is -227 dBc/Hz with less than 180 fs RMS jitter. It operates from 3.3 V and 5 V supply rails and is specified for -40 °C to +85 °C operation. The package is a RoHS-compliant 40-lead 6 mm by 6 mm SMT QFN with exposed paddle and matte tin lead finish.
