Programmable Digital

QPSK/16-QAM Modulator

AD9853

FEATURES

GENERAL DESCRIPTION

Universal Low Cost Solution for HFC Network

Return-Channel T_XFunction: 5 MHz–42 MHz/

5 MHz–65 MHz

165 MHz Internal Reference Clock Capability

Includes Programmable Pulse-Shaping FIR Filters and

Programmable Interpolating Filters

FSK/QPSK/DQPSK/16-QAM/D16-QAM Modulation

Formats

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.

Internal Reference Clock Multiplier

Integrated Reed-Solomon FEC Function

Programmable Randomizer/Preamble Function

Supports Interoperable Cable Modem Standards

Internal SINx/x Compensation

>50 dB SFDR @ 42 MHz Output Frequency (Single Tone)

Controlled Burst Mode Operation

+3.3 V to +5 V Single Supply Operation

Low Power: 750 mW @ Full Clock Speed (3.3 V Supply)

Space Saving Surface Mount Packaging

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.
