AD9852 FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
The AD9852 digital synthesizer is a highly integrated device that
uses advanced DDS technology, coupled with an internal high-
speed, high performance D/A converter and comparator to form a
digitally-programmable synthesizer function.When referenced to
an accurate clock source, the AD9852 generates a highly stable,
frequency/phase-programmable output sinewave that can be used
as an agile L.O. in communications, radar, and many other
applications. The AD9852's innovative high-speed DDS core
provides a 32-bit frequency tuning word, which results in an
output tuning resolution of .07 Hz, for a 300 MHz internal
reference clock input. The AD9852's circuit architecture allows
the generation of an output sinewave at up to one-third the clock
frequency, or 100 MHz, which can be digitally changed up to a
rate of 25 million new frequencies per second. The device also
provides 14-bits of digitally-controlled phase modulation.
The on-board 12-bit DAC, coupled with the innovative DDS
architecture, provides excellent output wideband and narrowband
SFDR. The AD9852’s programmable 4-20X reference clock PLL
generates the 300 MHz clock internally, from an external
reference clock. This saves the user the expense and difficulty of
implementing a 300 MHz clock source. The AD9850 uses
advanced CMOS technology to provide this high level of
functionality on <500 mW of power dissipation, at a maximum
internal clock rate of 300 MHz.
The AD9852 is available in a space-saving 44-pin TQFP surface
mount package. It is specified to operate over the extended
industrial temperature range of -40° to +85°C.
