The AD9986 is a highly integrated device with a 16-bit, 12 GSPS maximum sample rate RF DAC core, and a 12-bit, 6 GSPS rate RF ADC core. The AD9986 supports four transmitter channels and two receiver channels with four transmitter, two receiver (4T2R) configuration. The AD9986 is well suited for 2-antenna and 4-antenna transmitter applications requiring a wide bandwidth observation receiver path for the digital predistortion. The AD9986 supports up to a 6 GSPS complex transmit and receive data rate in single channel mode. The maximum radio channel bandwidth supported is 1.2 GHz and 2.4 GHz for the transmit and receive paths, respectively (4T2R). The AD9986 features a 16 lane, 24.75 Gbps JESD204C or 15.5 Gbps JESD204B serial data port, an on-chip clock multiplier, and digital signal processing capability targeted at multiband, direct-to-RF radio applications.

Product Lifecycle Recommended for New Designs
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.
Evaluation Kits (2)
The user guide describes the AD9081-FMCA-EBZ, AD9082-FMCA-EBZ, AD9986-FMCB-EBZ, and AD9988-FMCB-EBZ evaluation boards, which provide all of the support circuitry required to operate the AD9081, AD9082, AD9986, AD9988, AD9207, AD9209, or AD9177 in their various modes and configurations. The application software used to interface with the devices is also described. These evaluation boards connect to the Analog Devices, Inc., ADS9-V2EBZ for evaluation with the ACE software.
These evaluation boards can also interface to commercially available field-programmable gate array (FPGA) development boards from Xilinx® or Intel®. Information on how to use these platforms to evaluate the AD9081 or the AD9082 is available in the Using the AD-FMC-SDCARD section.
The ACE software allows the user to set up the MxFE® in various modes and to capture analog-to-digital converter(ADC) data for analysis. The DPGDownloaderLite software (included in ACE installation) generates and transmits vectors to the digital-to-analog converters (DACs), which can then be sent to a spectrum analyzer for further analysis.
For additional information, see the AD9081, AD9082, AD9986, AD9988, AD9207, AD9209, or AD9177 data sheets and the UG-1578, the device user guide, which must be consulted in conjunction with the user guide when using the evaluation boards.
When connected to a specified Analog Devices high speed converter evaluation board, the ADS9-V2EBZ works as a data capture/transmit board. Designed to support the highest speed JESD204B/C data converters, the FPGA on the ADS9-V2EBZ acts as the data receiver for high speed ADC's, and as the transmitter for high speed DAC's.

Software & Systems Requirements
API Device Drivers
Device Application Programming Interface (API) C code drivers provided as reference code that allows the user to quickly configure the product using high-level function calls. The library acts as an abstraction layer between the application and the hardware. The API is developed in C99 to ensure agnostic processor and operating system integration. Customers can port this application layer code to their embedded systems by integrating their platform-specific code base to the API HAL layer.
To request this software package, go to the Software Request Form signed in with your MyAnalog account and under “Target Hardware” select “High Speed Data Converters” and choose the desired API product package. You will receive an email notification once the software is provided to you.
Tools & Simulations
Software and Simulation
The JESD204B/C Mode Selector Tool is a simple command line-based Windows executable that can be used to narrow down the number of JESD204x modes to only include those modes that support the user’s specific application use case. The tool guides the user through a use case description flow chart and gives the user a small list of applicable transmit and/or receive modes to choose from. This tool is applicable to the AD9081, AD9082, AD9177, AD9207, AD9209, AD9986, and AD9988.
This command line executable tool generates a Verilog module which implements the JESD204 receive transport layer. The user specifies in a configuration file one or more modes to be supported by the transport layer module. These modes are defined as a set of JESD204 parameter values: L, M, F, S, N', and CF. The transport layer converts JESD204 lane data output from a JESD204 link layer IP to a data bus with a fixed width, containing interleaved virtual converter samples. Both JESD204B and JESD204C link layers are supported.
The JESD204x Frame Mapping Table Generator tool consists of two Windows executables that will allow the user to input any valid combination of JESD204x parameters (L, M, F, S, NP) in order to output a .csv file that illustrates the frame mapping of the JESD204x mode in table format. There is an executable that allows the user to input a single JESD204x mode and another, that allows the user to input the parameters for multiple JESD204x modes in a specified .csv format in order to output a .csv file that illustrates the frame mapping of each of the JESD204x modes that were input into separate tables.
