a Programmable Digital QPSK/16-QAM Modulator AD9853 FEATURES GENERAL DESCRIPTION Universal Low Cost Solution for HFC Network The AD9853 integrates a high speed direct-digital synthesizer Return-Channel TX Function: 5 MHz–42 MHz/ (DDS), a high performance, high speed digital-to-analog con- 5 MHz–65 MHz verter (DAC), digital filters and other DSP functions onto a 165 MHz Internal Reference Clock Capability single chip, to form a complete and flexible digital modulator Includes Programmable Pulse-Shaping FIR Filters and device. The AD9853 is intended to function as a modulator in Programmable Interpolating Filters network applications such as interactive HFC, WLAN and FSK/QPSK/DQPSK/16-QAM/D16-QAM Modulation MMDS, where cost, size, power dissipation, functional integra- Formats tion and dynamic performance are critical attributes. 6؋ Internal Reference Clock Multiplier The AD9853 is fabricated on an advanced CMOS process and Integrated Reed-Solomon FEC Function.
