产品详情

The AD9522-51 provides a multioutput clock distribution function with subpicosecond jitter performance, along with an on-chip PLL that can be used with an external VCO.   

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 AD9520-5 is an equivalent part to the AD9522-5 featuring LVPECL/CMOS drivers instead of LVDS/CMOS drivers.

1The AD9522 is used throughout this data sheet to refer to all the members of the AD9522 family. However, when AD9522-5 is used, it is referring to that specific member of the AD9522 family.
