AD9125:  Dual, 16-Bit, 1000 MSPS, TxDAC+® Digital-to-Analog Converter

Product Details

Product Status:Recommended for New Designs

The AD9125 is a dual, 16-bit, high dynamic range TxDAC+® digital-to-analog converter (DAC) that provides a sample rate of 1000 MSPS, permitting a multicarrier generation up to the 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 ADL537x F-MOD series from Analog Devices, Inc. A 4-wire serial port interface allows programming/readback of many inter-nal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9125 comes in a 72-lead LFCSP.


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.
    3. The current outputs are easily configured for various single-ended or differential circuit topologies.
    4. Flexible CMOS digital interface allows the standard 32- wire bus to be reduced to a 16-wire bus.
Applications
  • Wireless infrastructure
  • W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM, LTE
  • Digital high or low IF synthesis
  • Transmit diversity
  • Wideband communications: LMDS/MMDS, point-to-point
  • Cable modem termination systems
