Dual 16-Bit, 1.0 GSPS

D/A Converter

AD9779

Preliminary Technical Data

DAC that provides a sample rate of 1 GSPS, permitting multi

carrier generation up to its Nyquist frequency. It includes features

optimized for direct conversion transmit applications, including

complex digital modulation and gain and offset compensation. The

DAC outputs are optimized to interface seamlessly with analog

quadrature modulators such as the AD8349. A serial peripheral

interface (SPI) provides for programming many internal

FEATURES

• 1.8/3.3 V Single Supply Operation

• Low power: 950mW (I_OUTFS= 20 mA; f_DAC= 1 GSPS, 4×

Interpolation

• DNL = 1.5 LSB, INL = 5.0 LSB

• SFDR =82 dBc to f_OUT= 100 MHz

• ACLR = 87 dBc @ 80 MHz IF

parameters and also enables read-back of status registers. The

output current can be programmed over a range of 10mA to 30mA.

The AD9779 is manufactured on an advanced 0.18µm CMOS

process and operates from 1.8V and 3.3V supplies for a total power

consumption of 950mW. It is supplied in a 100-lead QFP package.

• CMOS data interface with Autotracking Input Timing

• Analog Output: Adjustable 10-30mA (RL=25 Ω to 50 Ω)

• 100-lead Exposed Paddle TQFP Package

• Multiple Chip Synchronization Interface

• 84dB Digital Interpolation Filter Stopband Attenuation

• Digital Inverse Sinc Filter

PRODUCT HIGHLIGHTS

Ultra-low noise and Intermodulation Distortion (IMD) enable

high quality synthesis of wideband signals from baseband to high

intermediate frequencies.

APPLICATIONS

• Wireless Infrastructure

Direct Conversion

Single-ended CMOS interface supports a maximum input rate of

300 MSPS with 1x interpolation.

Transmit Diversity

• Wideband Communications Systems:

Point-to-Point Wireless, LMDS

Manufactured on a CMOS process, the AD9779 uses a proprietary

switching technique that enhances dynamic performance.

PRODUCT DESCRIPTION

The current outputs of the AD9779 can be easily configured for

various single-ended or differential circuit topologies.

The AD9779 is a dual 16-bit high performance, high frequency
