Features and Benefits
- Simple evaluation of the AD9166 vector signal generator IC with only a single connection needed
- Integrated on-board clocking, featuring the ADF4372
- Integrated on-board power and power sequencer
The evaluation board connects to an ADS7-V2EBZ pattern generator for quick evaluation of the AD9166, a high speed, vector signal generator. The ADS7-V2EBZ automatically formats the signal data and sends it to the evaluation board across a JESD204B link, which simplifies evaluation of the device. The evaluation board is powered by the field-programmable gate array (FPGA) mezzanine card (FMC) power supply provided through the ADS7-V2EBZ. The board can also interface to commercially available field- programmable gate array (FPGA) development boards from Xilinx® or Intel®.
The evaluation board includes a clock buffer, the HMC7044, which provides a reference clock to the ADS7-V2EBZ and SYSREF± signals to both the ADS7-V2EBZ and the digital-to-analog converter (DAC) integrated inside the AD9166. The on-board ADF4372 generates a sampling clock for the DAC.
The reference and sampling clocks can be connected externally through the on-board Subminiature Version A (SMA) ports. SYSREF± can be connected from an external source, such as an FPGA development kit, across the FMC connector to the AD9166.
The various clock configurations are outlined in Figure 3 of the user guide. The clock paths can be selected by soldering 0 Ω resistors (jumpers) in the correct locations on the evaluation board and configuring the ADF4372 and HMC7044 as described in the On-Board Clocking section of the user guide.
Complete specifications for the AD9166 can be found in the AD9166 data sheet available from Analog Devices, Inc., and must be consulted in conjunction with the user guide when using the evaluation board.
