The AD9522-3BCPZ is a 12-output Clock Generator with 2GHz integrated voltage-controlled oscillator (VCO). It provides a multi output clock distribution function with sub pico second jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 1.72 to 2.25GHz. An external 3.3/5V VCO/VCXO of up to 2.4GHz can also be used. The AD9522 serial interface supports both SPI and I2C ports. The AD9522 features 12 LVDS outputs in four groups. Any of the 800MHz LVDS outputs can be reconfigured as two 250MHz CMOS outputs. Each group of outputs has a divider that allows both the divide ratio (from 1 to 32) and the phase (coarse delay) to be set.
