Description
- Product Details
- 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 ADL5375 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 AD9785/AD9787/AD9788 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.
- Product Highlights
- 1. Low noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies.
- 2. Proprietary DAC output switching technique enhances dynamic performance.
- 3. CMOS data input interface with adjustable setup and hold.
- 4. Low power complex 32-bit numerically controlled oscillators (NCOs).
- Applications
- Wireless infrastructure
- W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM
- Digital high or low IF synthesis
- Transmit diversity
- Wideband communications
- LMDS/MMDS, point-to-point
- ### Features and Benefits
- Analog output: adjustable 8.7 mA to 31.7 mA, RL = 25 Ω to 50 Ω
- Low power, fine complex NCO allows carrier placement anywhere in DAC bandwidth while adding <300 mW power
- Auxiliary DACs allow I and Q gain matching and offset control
- Includes programmable I and Q phase compensation
- Internal digital upconversion capability
- Multiple chip synchronization interface
- High performance, low noise PLL clock multiplier
- Digital inverse sinc filter
- 100-lead, exposed pad TQFP package
