GENERAL DESCRIPTION
The AD9853 integrates a high speed direct-digital synthesizer
(DDS), a high performance, high speed digital-to-analog con-
verter (DAC), digital filters and other DSP functions onto a
single chip, to form a complete and flexible digital modulator
device. The AD9853 is intended to function as a modulator in
network applications such as interactive HFC, WLAN and
MMDS, where cost, size, power dissipation, functional integra-
tion and dynamic performance are critical attributes.
The AD9853 is fabricated on an advanced CMOS process and
it sets a new standard for CMOS digital modulator performance.
The device is loaded with programmable functionality and
provides a direct interface port to the AD8320, digitally-
programmable cable driver amplifier. The AD9853/AD8320
chipset forms a highly integrated, low power, small footprint
and cost-effective solution for the HFC return-path requirement
and other more general purpose modulator applications.
The AD9853 is available in a space saving surface mount pack-
age and is specified to operate over the extended industrial
temperature range of –40
°
C to +85
°
C.
