The is a low noise, wide band, Fractional N Phase-Locked-Loop (PLL) that features an integrated Voltage Controlled Oscillator (VCO ) with a fundamental frequency of 2800 M Hz - 4200 M Hz, and an integrated VCO Output Divider (divide by 1/2/4/6.../60/62), that together allow the to generate frequencies from 45 M Hz to 1050 M Hz, from 1400 M Hz to 2100 M Hz, and from 2800 M Hz to 4200 M Hz. The integrated Phase Detector (P D) and delta-sigma modulator, capable of operating at up to 100 M Hz, permit wider loop-bandwidths with excellent spectral performance.The features industry leading phase noise and spurious performance, across all frequencies, that enable it to minimize blocker effects, and improve receiver sensitivity and transmitter spectral purity. The superior noise floor (< -170 dBc/ Hz) makes the an ideal source for a variety of applications - such as; L O for RF mixers, a clock source for high frequency data-converters, or a tunable reference source for ultra-low spurious applications.Additional features of the include RF output power control from 0 to 6 dB (~2 dB steps), output Mute function, and a delta-sigma modulator Exact Frequency Mode which enables users to generate output frequencies with 0 Hz frequency error.For theory of operation and register map refer to the "PLLs with Integrated VCO s - RF VCO s Operating Guide".
