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 two250 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.The AD9522 is available in a 64-lead LFCSP and can be operatedfrom a single 3.3 V supply. The external VCO can have anoperaTIng voltage up to 5.5 V.The AD9522 is specified for operaTIon over the standard industrialrange of −40°C to +85°C.The AD9520-0 is an equivalent part to the AD9522-0 featuringLVPECL / CMOS drivers instead of LVDS / CMOS drivers.
