GENERAL DESCRIPTION
The AD9856 integrates a high-speed direct-digital synthesizer
(DDS), a high-performance, high-speed 12-bit Digital-to-Analog
converter (DAC), clock multiplier circuitry, digital filters, and
other DSP functions onto a single chip, to form a complete
quadrature digital upconverter device. The AD9856 is primarily
intended to function as a universal upstream and downstream I/Q
modulator for interactive HFC cable network applications, where
cost, size, power dissipation, and dynamic performance are
critical attributes.
The AD9856 is fabricated on an advanced CMOS process and it
delivers an exceptional level of mixed signal performance. The
device provides a precision digital modulation and upconvert
function with 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 Tx requirement.
The AD9856 is available in a space-saving surface mount
package and is specified to operate over the extended industrial
temperature range of -40° to +85°C.
