16-Bit, 12 GSPS, RF Digital-to-Analog Converter
The AD9162 is a high performance, 16-bit digital-to-analog converter (DAC) that supports data rates to 6 GSPS. The DAC core is based on a quad-switch architecture coupled with a 2× interpolator filter that enables an effective DAC update rate of up to 12 GSPS in some modes. The high dynamic range and bandwidth makes these DACs ideally suited for the most demanding high speed radio frequency (RF) DAC applications.
In baseband mode, wide bandwidth capability combines with high dynamic range to support DOCSIS 3.1 cable infrastructure compliance from the minimum of two carriers to full maximum spectrum of 1.794 GHz. A 2× interpolator filter (FIR85) enables the AD9161/AD9162 to be configured for lower data rates and converter clocking to reduce the overall system power and ease the filtering requirements. In Mix-Mode™ operation, the AD9161/ AD9162 can reconstruct RF carriers in the second and third Nyquist zones up to 7.5 GHz while still maintaining exceptional dynamic range. The output current can be programmed from 8 mA to 38.76 mA. The AD9161/AD9162 data interface consists of up to eight JESD204B serializer/deserializer (SERDES) lanes that are programmable in terms of lane speed and number of lanes to enable application flexibility.
A serial peripheral interface (SPI) can configure the AD9162 and monitor the status of all registers. The AD9162 is offered in an 165-ball, 8.0 mm × 8.0 mm, 0.5 mm pitch, CSP_BGA package and in a 169-ball, 11 mm × 11 mm, 0.8 mm pitch, CSP_BGA package, including a leaded ball option.

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 AD9161, AD9162, AD9163, and AD9164 evaluation boards are all FMC form-factor boards with FMC connector that complies to the Vita 57.1 standard. There are three variants of the board (-FMC, -FMCB, -FMCC) that accommodate slightly different Bills of Material (BOMs).
- The -FMC boards are designed for the 8x8mm package variant of the AD9162 and AD9164 and use a Marki Microwave wideband balun on the DAC output.
- The -FMCB boards are designed for the same 8x8mm package variant of the AD9162 and AD9164, and use a Mini-Circuits balun on the DAC output.
- The -FMCC boards are designed for the 11x11mm package variant and accommodates all four of the AD9161, AD9162, AD9163, and AD9164. It also uses a Mini-Circuits balun on the DAC output.
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 AD9162 and AD9164 boards have 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 ADF4355 PLL, 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.
Evaluation Boards Differences
The differences between the AD9161, AD9162, AD9163, and AD9164 FMC boards are the DAC, package, and its output Balun are shown in the User Guide. For example, the AD916x-FMCx-EBZ uses the Marki BAL-0009SMG and the AD916x-FMCB-EBZ uses the Mini-Circuits TC1-1-43A+.
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.
