The AD9737A/AD9739A are 11-bit and 14-bit, 2.5 GSPS high performance RF DACs that are capable of synthesizing wideband signals from dc up to 3 GHz. The AD9737A/AD9739A are pin and functionally compatible with the AD9739 with the exception that the AD9737A/AD9739A do not support synchronization or RZ mode, and are specified to operate between 1.6 GSPS and 2.5 GSPS.

By elimination of the synchronization circuitry, some nonideal artifacts such as images and discrete clock spurs remain stationary on the AD9737A/AD9739A between power-up cycles, thus allowing for possible system calibration. AC linearity and noise performance remain the same between the AD9739 and the AD9737A/AD9739A.

The inclusion of on-chip controllers simplifies system integration. A dual-port, source synchronous, LVDS interface simplifies the digital interface with existing FGPA/ASIC technology. On-chip controllers are used to manage external and internal clock domain variations over temperature to ensure reliable data transfer from the host to the DAC core. A serial peripheral interface (SPI) is used for device configuration as well as readback of status registers.

The AD9737A/AD9739A are manufactured on a 0.18 µm CMOS process and operate from 1.8 V and 3.3 V supplies. They are supplied in a 160-ball chip scale ball grid array for reduced package parasitics.

Product Highlights

  1. Ability to synthesize high quality wideband signals with bandwidths of up to 1.25 GHz in the first or second Nyquist zone.
  2. A proprietary quad-switch DAC architecture provides exceptional ac linearity performance while enabling mixmode operation.
  3. A dual-port, double data rate, LVDS interface supports the maximum conversion rate of 2500 MSPS.
  4. On-chip controllers manage external and internal clock domain skews.
  5. Programmable differential current output with an 8.66 mA to 31.66 mA range.

Applications

  • Broadband communications systems
    • DOCSIS CMTS systems
  • Military jammers
  • Instrumentation, automatic test equipment
  • Radar, avionics

Product Detail

The ADS7-V2 Evaluation Board was developed to support the evaluation of Analog Devices high speed A/D converters, D/A converters and Transceivers with JESD204B bit rates up to 13.1 Gbps. The Quick Start Wiki site listed below provides a high level overview of the platform. In addition, each use case of the board has its own section (e.g. Using the ADS7-V2 for High Speed A/D Converter Evaluation). The ADS7-V2 is intended to be used only with specified Analog Devices Evaluation Boards. The ADS7-V2 is not intended to be used as a development platform, and no support is available for standalone operation. Please refer to Xilinx and its approved distributors for FPGA Development Kits
