GENERAL DESCRIPTION
The AD9520-41 provides a multioutput clock distribution
function with subpicosecond jitter performance, along with an
on-chip PLL and VCO. The on-chip VCO tunes from 1.4 GHz to
1.8 GHz. An external 3.3 V/5 V VCO/VCXO of up to 2.4 GHz
can also be used.

Figure 1.
The AD9520 serial interface supports both SPI and IC ports.
An in-package EEPROM, which can be programmed through the
serial interface, can store user-defined register settings for
power-up and chip reset.
The AD9520 features 12 LVPECL outputs in four groups. Any
of the 1.6 GHz LVPECL outputs can be reconfigured as two
250 MHz CMOS outputs. If an application requires LVDS
drivers instead of LVPECL drivers, refer to the AD9522.
Each group of three outputs has a divider that allows both the
divide ratio (from 1 to 32) and the phase offset or coarse time
delay to be set.
The AD9520 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 of up to 5.5 V. A separate output driver power
supply can be from 2.375 V to 3.465 V.
The AD9520-4 is specified for operation over the standard
industrial range of 40°C to +85°C.
AD9520 is used throughout this data sheet to refer to all the members of the AD9520 family. However, when AD9520-4 is used, it refers to that specific member of the
AD9520 family.
