The AD9988 is a highly integrated device with four 16-bit, 12 GSPS maximum sample rate, RF digital-to-analog converter (DAC) cores, and four 12-bit, 4 GSPS rate, RF analog-to-digital converter (ADC) cores. The device supports four transmitter channels and four receiver channels with a 4T4R configuration. This product is well suited for four-antenna TDD transmitter applications, where the receiver path can be shared between receiver and observation modes. The GPIO pins can be configured and toggled to support different user modes, while phase coherency is maintained. The maximum radio channel bandwidth supported is 1.2 GHz in a 4T4R configuration and a sample resolution of 16 bits. The AD9988 features a 16-lane 24.75 Gbps JESD204C or 15.5 Gbps JESD204B serial data port that allows up to eight lanes per transmit/receive link, an on-chip clock multiplier, and digital signal processing capability targeted at multiband direct to RF radio applications.

Evaluation Kits (3)
The AD9081-FMCA-EBZ evaluation board includes all of the support circuitry required to operate the AD9081 in various modes and configurations. The application software used to interface with the device is also described. The AD9081-FMCA-EBZ evaluation board connects to the Analog Devices, Inc., ADS9-V2EBZ for evaluation with the ACE software. The 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 AD9082 is available in the Using the AD-FMC-SDCARD section.
The ACE software allows the user to set up the AD9081 or AD9082 in various modes, and capture analog-to-digital converter (ADC) data for analysis. The DPGDownloaderLite software generates and transmits vectors to the DACs, which can then be sent to a spectrum analyzer for further analysis. For more details, see the AD9081 and AD9082 data sheets, which must be consulted in conjunction with this user guide when using the evaluation boards.
Features & Benefits
- Fully functional evaluation boards for the AD9081
- PC software for control with ACE software
- On-board clocking provided by the HMC7044 manages device and FPGA clocking
- Option to switch to external direct clocking
When connected to a specified Analog Devices high speed converter evaluation board, the ADS8-V3EBZ works with ADI evaluation software as a data capture/transmit and control interface. Designed to support high speed data converters with JESD204B/C serial line rates up to 16.375 Gbps, the FPGA on the ADS8-V3EBZ acts as the data receiver for high speed ADC's, and as the transmitter for high speed DAC's.
Limited to use cases where lane rates are less than 16.375 Gbps due to the FPGA capability. (Applies to AD9081 and AD9082.)

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
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.
