Product Details

The AD9082 mixed signal front-end (MxFE®) is a highly integrated device with a 16-bit, 12 GSPS maximum sample rate, RF digital-to-analog converter (DAC) core, and 12-bit, 6 GSPS maximum sample rate, RF analog-to-digital converter (ADC) cores. The AD9082 is well suited for applications requiring both wideband ADCs and DACs to process signal(s) having wide instantaneous bandwidth. The device features eight transmit lanes and eight receive lanes that support 24.75 Gbps/lane JESD204C or 15.5 Gbps/lane JESD204B standards. The device also has an on-chip clock multiplier and digital signal processing (DSP) capability targeted at either wideband or multiband, direct to RF applications. The DSP datapaths can be bypassed to allow a direct connection between the converter cores and the JESD204B/C data transceiver port. The device also features low latency loopback, frequency hopping modes, and datapath multiplexer (mux) configurations useful for phase array radar system and electronic warfare applications. Two models for the AD9082 are offered. The 4D2AC model supports four DACs and two ADCs. The 2D2AC model supports two DACs and two ADCs.

APPLICATIONS

  • Wireless communications infrastructure
  • Microwave point-to-point, E-band and 5G mmWave
  • Broadband communications systems
  • DOCSIS 3.1 and 4.0 CMTS
  • Phased array radar and electronic warfare
  • Electronic test and measurement systems

    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

    S-Parameters

    AD9081/AD9082/AD9986/AD9988 RFIO Models

    Keysight ADS workbook and s-parameter files for simulating the frequency response of the AD908x DAC, ADC, and CLK interfaces. See Application note AN-2065: Optimizing RF performance of the AD9081 and AD9082” for instructions on how to use the models.

    Design Tools

    MxFE JESD204 Mode Selector Tool (Rev. E)

    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.

    ADIsimPLL™

    ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
