GENERAL DESCRIPTION
The AD9520-11
provides a multioutput clock distribution
function with subpicosecond jitter performance, along with an
on-chip PLL and VCO. The on-chip VCO tunes from 2.27 GHz
to 2.65 GHz. An external 3.3 V/5 V VCO/VCXO of up to 2.4 GHz
can also be used, MxFEs
High performance wireless transceivers
ATE and high performance instrumentation
Broadband infrastructures
The AD9520 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 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.
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 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 up to 5.5 V. A separate output driver power
supply can be from 2.375 V to 3.465 V.
The AD9520 is specified for operation over the standard industrial
range of −40°C to +85°C.
