The AD9172 is a high performance, dual, 16-bit digital-to-analog converter (DAC) that supports DAC sample rates to 12.6 GSPS. The device features an 8-lane, 15 Gbps JESD204B data input port, a high performance, on-chip DAC clock multiplier, and digital signal processing capabilities targeted at single-band and multiband direct to radio frequency (RF) wireless applications.

The AD9172 features three complex data input channels per RF DAC that are bypassable. Each data input channel includes a configurable gain stage, an interpolation filter, and a channel numerically controlled oscillator (NCO) for flexible, multiband frequency planning. The device supports up to a 1.5 GSPS complex data rate per input channel and is capable of aggregating multiple complex input data streams up to a maximum complex data rate of 1.5 GSPS. Additionally, the AD9172 supports ultrawide bandwidth modes bypassing the channelizers to provide maximum data rates of up to 3.08 GSPS (with 16-bit resolution) and 4.1 GSPS (with 12-bit resolution).

The AD9172 is available in a 144-ball BGA_ED package.

PRODUCT HIGHLIGHTS

  1. Supports single-band and multiband wireless applications with three bypassable complex data input channels per RF DAC at a maximum complex input data rate of 1.5 GSPS. One independent NCO per input channel.
  2. Ultrawide bandwidth channel bypass modes supporting up to 3 GSPS data rates with 16-bit resolution and 4 GSPS with 12-bit resolution.
  3. Low power dual converter decreases the amount of power consumption needed in high bandwidth and multichannel applications.

APPLICATIONS

  • Wireless communications infrastructure
    • Multiband base station radios
    • Microwave/E-band backhaul systems
  • Instrumentation, automatic test equipment (ATE)
  • Radars and jammers

Product Detail

The AD9171, AD9172, and AD9173 evaluation boards are FMC form-factor boards with FMC connectors that comply to the Vita 57.1 standard. The FMC boards use a Mini-Circuits balun on the DAC output.

To operate the evaluation board, the user must attach the board to a compatible FMC carrier board, such as those provided by FPGA vendors. Analog Devices produces an FPGA carrier called the ADS7-V2, which serves as a digital pattern generator or data source as well as the power supply for the boards. The AD917x board has an option to be powered from a lab power supply when used in a special NCO-only mode. This operation is described in more detail in the User's Guide, linked on the wiki site. The user must be able to observe the DAC output on a spectrum analyzer. A low noise clock source is provided on the evaluations boards, the HMC7044 clock synthesizer, and an option exists for the user to supply a low jitter external sine or square wave clock as a clock source instead. The evaluation board comes with software, called ACE, which allows the user to program the SPI port. Via the SPI port, the DUT (and clock circuitry) can be programmed into any of its various operating modes. It also comes with the DAC Software Suite which includes the DPGDownloader for vector generation, download, and transmission to the evaluation board when using the ADS7-V2.
