Dual 12-/14-/16-Bit,

1 GSPS, Digital-to-Analog Converters

AD9776/AD9778/AD9779

FEATURES

GENERAL DESCRIPTION

Low power: 1.0 W @ 1 GSPS, 600 mW @ 500 MSPS,

full operating conditions

SFDR = 78 dBc to f_OUT= 100 MHz

Single carrier WCDMA ACLR = 79 dBc @ 80 MHz IF

Analog output: adjustable 8.7 mA to 31.7 mA,

R_L= 25 Ω to 50 Ω

Novel 2×, 4×, and 8× interpolator/coarse complex modulator

allows carrier placement anywhere in DAC bandwidth

Auxiliary DACs allow control of external VGA and offset control

Multiple chip synchronization interface

High performance, low noise PLL clock multiplier

Digital inverse sinc filter

The AD9776/AD9778/AD9779 are dual, 12-/14-/16-bit, high

dynamic range, digital-to-analog converters (DACs) that pro-

vide a sample rate of 1 GSPS, permitting multicarrier generation

up to the Nyquist frequency. They include 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 quad-

rature modulators such as the AD8349. A serial peripheral interface

(SPI®) provides for programming/readback of many internal

parameters. Full-scale output current can be programmed over a

range of 10 mA to 30 mA. The devices are manufactured on an

advanced 0.18 μm CMOS process and operate on 1.8 V and

3.3 V supplies for a total power consumption of 1.0 W. They are

enclosed in 100-lead TQFP packages.

100-lead, exposed paddle TQFP package

APPLICATIONS

Wireless infrastructure

WCDMA, CDMA2000, TD-SCDMA, WiMax, GSM

Digital high or low IF synthesis

Internal digital upconversion capability

Transmit diversity

PRODUCT HIGHLIGHTS

1. Ultralow noise and intermodulation distortion (IMD)

enable high quality synthesis of wideband signals from

baseband to high intermediate frequencies.

2. A proprietary DAC output switching technique enhances

dynamic performance.

Wideband communications: LMDS/MMDS, point-to-point

3. The current outputs are easily configured for various

single-ended or differential circuit topologies.

4. CMOS data input interface with adjustable set up and hold.

5. Novel 2×, 4×, and 8× interpolator/coarse complex

modulator allows carrier placement anywhere in DAC

bandwidth.
