The AD9522 serial interface supports both SPI and I2C® ports.
An in-package EEPROM can be programmed through the
serial interface and store user-defined register settings for
power-up and chip reset.
The AD9522 features 12 LVDS outputs in four groups. Any of
the 800 MHz LVDS outputs can be reconfigured as two
250 MHz 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.
The AD9522 is available in a 64-lead LFCSP and can be operated
from a single 3.3 V supply. The external VCO can have an
operating voltage up to 5.5 V.
The AD9522 is specified for operation over the standard industrial
range of −40°C to +85°C.
The AD9520-0 is an equivalent part to the AD9522-0 featuring
LVPECL / CMOS drivers instead of LVDS / CMOS drivers.
