Dual, 16-Bit, 1200 MSPS, TxDAC+® Digital-to-Analog Converter

Manufactured by:

Product Details

The AD9122 is a dual 16-bit, high dynamic range, digital-to-analog converter (DAC) that provides a sample rate of 1200 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 provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9122 comes in a 72-lead LFCSP.

The AD9122-EP supports defense and aerospace applications (AQEC).

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 LVDS digital interface allows the standard 32-wire bus to be reduced to ½ or ¼ of the width.


  • Wireless infrastructure
  • Digital high or low IF synthesis

Product Details

This board is no longer available for ordering.

The AD-FMCOMMS1-EBZ high-speed analog module is designed to showcase the latest generation high-speed data converters. The AD-FMCOMMS1-EBZ provides the analog front-end for a wide range of compute-intensive FPGA-based radio applications.

The AD-FMCOMMS1-EBZ is an analog front end hardware platform that addresses a broad range of research, academic, industrial and defense applications. The AD-FMCOMMS1-EBZ enables RF applications from 400MHz to 4 GHz. The module is customizable to a wide range of frequencies by software without any hardware changes, providing options for GPS or IEEE 1588 Synchronization, and MIMO configurations.

When combined with the Xilinx ZYNQ® Software-Defined Radio Kit, AD-FMCOMMS1-EBZ enables a variety of wireless communications functions at the physical layer, from baseband to RF. With up to 4 GB of flash storage space, 512 MB of RAM, Gigabit Ethernet interface (depending on the base platform) and a Linux image built specifically for the AD-FMCOMMS1-EBZ, you can get everything you need for a easy out of the box experience. The platform offers enough flexibility for many applications, and supports streaming data, and standard web interfaces to analyze transmitted RF data.
