Dual, 16-Bit, 12.6 GSPS RF DAC with Channelizers
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.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The AD9172 evaluation board is an FMC form-factor board with FMC connector that complies to the Vita 57.1 standard.
To operate the evaluation boards, 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 AD9172 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. 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 sythesizer, 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.
Documentation and software updates for using High-Speed DAC Evaluation Boards are included in individual, self-extracting update files.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
