AD9522-3BCPZ Datasheet PDF - ADI

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.
