Hot-selling and scarce AD9522-0BCPZ 12 LVDS/24 CMOS Output Clock Generator 64LFCSP spot stock

Product Descriptions

The AD9522-0¹ provides a multioutput clock distributionfunction with subpicosecond jitter performance, along with anon-chip PLL and VCO. The on-chip VCO tunes from 2.53 GHzto 2.95 GHz.An external 3.3 V/5 V VCO/VCXO of up to 2.4 GHzcan also be used .

The AD9522 serial interface supports both SPI and I2C® ports .An in-package EEPROM can be programmed through theserial interface and store user-defined register settings forpower-up and chip reset .

The AD9522 features 12 LVDS outputs in four groups. Any ofthe 800 MHz LVDS outputs can be reconfigured as two 250 MHz CMOS outputs .

Each group of outputs has a divider that allows both the divideratio (from 1 to 32) and the phase (coarse delay) to be set.
