AD9785/AD9787/AD9788分别是12/14/16位、高动态范围TxDAC®器件,提供800 MSPS采样速率,可以产生最高达奈奎斯特频率的多载波。这些器件具有针对直接变频传输应用进行优化的特性,包括复合数字调制以及增益、相位与失调补偿。DAC输出经过优化,可以与模拟正交调制器无缝接口,例如ADI公司的ADL537x系列调制器。利用串行外设接口(SPI)可以对许多内部参数进行编程和回读。满量程输出电流可以在10 mA至30 mA范围内进行编程。AD978x系列采用0.18 µm CMOS工艺制造,采用1.8 V和3.3 V电源供电,并提供100引脚TQFP封装。
The AD9785/AD9787/AD9788 are 12-bit, 14-bit, and 16-bit, high dynamic range TxDAC® devices, respectively, that provide a sample rate of 800 MSPS, permitting multicarrier generation up to the Nyquist frequency. Features are included for optimizing direct conversion transmit applications, including complex digital modulation, as well as gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x family from Analog Devices, Inc. A serial peripheral interface (SPI) provides for programming and readback of many internal parameters. Full-scale output current can be programmed over a range of 10 mA to 30 mA. The AD978x family is manufactured on a 0.18 μm CMOS process and operates from 1.8 V and 3.3 V supplies. It is enclosed in a 100-lead TQFP package.
