ADS7-V1/-V2 for High-Speed DAC Evaluation

The ADS7-V1 and ADS7-V2 platforms are used to evaluate many types of Analog Devices components and systems. The information on this page applies only to High-Speed DAC evaluation. For information on using the ADS7 with High-Speed ADC devices, please check these pages for the ADS7-V1 and ADS7-V2.

The ADS7-V1 and ADS7-V2 are devices designed to support the evaluation of Analog Devices' High-Speed Digital-to-Analog Converters (DAC). The device is connected to a PC over USB, and allows a user to download a data vector into the ADS7, which is then played out to an attached DAC evaluation board at full speed.

Please note: Analog Devices' pattern generators and high-speed DAC evaluation boards are designed and sold solely to support an efficient and thorough means by which to evaluate Analog Devices high speed DACs in a lab environment for a wide range of end applications. Any application or use of the pattern generators and/or high-speed DAC evaluation boards, other than specified above, will not be supported.

This page describes the hardware of ADS7-V1 and ADS7-V2. The device can be driven from many different software applications. For more information on the software, please see the High-Speed DAC Software Suite documentation.

For information on the DPG3, the predecessor to the ADS7 platforms, please see the DPG3 page.

Ordering Code

The part number for the ADS7-V1 is ADS7-V1EBZ. The part number for the ADS7-V2 is ADS7-V2EBZ.

Hardware Differences

The ADS7-V1 has two FMC connectors, while the ADS7-V2 has only one. The two platforms have the same specifications per FMC connector, the ADS7-V1 simply has two of them. Most evaluations will only need the ADS7-V2.

Hardware Specifications

Please note that not all hardware options and specifications are supported with any particular evaluation board or software package. Specifications are subject to change without notice.

  • Converter Interfaces
    • LVDS Interface (x2 for the ADS7-V1)
      • 32-bits
      • Up to 1.6Gbps per bit (800MHz DDR)
      • Same connector and pinout as DPG3 when paired with the DAC FMC Adapter.
    • High-Speed Serial Interface (x2 for the ADS7-V1) (For JESD204 Converters)
      • 8 Tx lanes
      • Up to 13.1Gbps per lane
  • Memory
    • Dual 2GB DDR3 SO-DIMM
    • Amount of memory available for pattern download depends on various factors, including PC specifications and converter settings
  • PC Interface
    • USB 2.0 “B” connector
  • Specified for operation at 25ºC only

Some PCs with early USB 3.0 SuperSpeed ports have been unable to communicate reliably with an ADS7. On these PCs, the standard USB 2.0 ports (without the logo) should be used with the ADS7.

Connector Pinouts

The ADS7 platforms utilize the standard VITA 57.1 “FMC” connector. See the VITA FMC page for more information.

Other Connectors, Buttons, and Switches

The other connectors on the board are not enabled. Do not connect anything to these connectors. Buttons and switches on the board should be left in their factory-set position.

Firmware Update

The firmware of the ADS7 can be updated when new features or fixes are available. To update the firmware, click the Advanced/Debug button in DPGDownloader. Click the Update button in the Firmware section, and select the new firmware file.

On the ADS7-V1, do not interrupt the firmware update process. The unit may become inoperable and will need to be returned to Analog Devices for repair.

The ADS7-V2 has a redundant firmware feature. If a firmware update is interrupted, the unit will revert to the original factory version, and the firmware update can be performed again.

Support

Please contact DPG Support with any additional questions regarding the ADS7-V1/-V2 or DAC Software Suite.
