AD9853
AD9853 is Programmable Digital OPSK/16-QAM Modulator manufactured by Analog Devices.
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 plete 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...
