Product Details

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.

Software & Systems Requirements

Device Drivers

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

Design Tools

MxFE JESD204 Mode Selector Tool

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.

Companion Transport Layer RTL Code Generator Tool (Rev. 1.0)

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.

JESD204x Frame Mapping Table Generator

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.
