Dual, 12-/14-/16-Bit,  
1.0 GSPS D/A Converter  
AD9776/AD9778/AD9779  
GENERAL DESCRIPTION  
FEATURES  
DAC output sample rate: 1 GSPS  
1.8 V/3.3 V single supply operation  
Low power: 1.0 W @ 1 GSPS, 600 mW @ 500 MSPS,  
full operating conditions  
SFDR = 78 dBc to fOUT = 100 MHz  
Single carrier WCDMA ACLR = 79 dBc @ 80 MHz IF  
CMOS data input interface with adjustable setup and hold  
Analog output: adjustable 8.7 mA to 31.7 mA,  
RL = 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 DACs that provide a sample rate of 1 GSPS, thus  
permitting multicarrier generation up to its 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 quadrature modulators such as  
the AD8349. A serial peripheral interface (SPI) provides for  
programming/readback of many internal parameters. The  
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 from 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  
PRODUCT HIGHLIGHTS  
APPLICATIONS  
Wireless infrastructure  
Digital high or low IF synthesis  
Internal digital upconversion capability  
Transmit diversity  
Wideband communications systems  
point-to-point wireless, LMDS  
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.  
3. The current outputs can be easily configured for various  
single-ended or differential circuit topologies.  
Multicarrier WCDMA  
Multicarrier GSM
