The AD9853 integrates a high speed direct-digital synthesizer (DDS), a high performance, high speed digital-to-analog converter (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 integration 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, digitallyprogrammable 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 package and is specified to operate over the extended industrial temperature range of 40C to +85C.
