제목 없음.jpg

The AD/DA Data Conversion Card was created to provide a set of Analog to Digital and Digital to Analog interfaces including an Audio CODEC interface. The High Speed Mezzanine Card (HSMC) can be used to develop DSP applications with Altera Development boards and Terasic Development boards (e.g.DE3) that feature the HSMC connector.


  • One High Speed Mezzanine Card (HSMC) connector for interface conversion, which is fully compatible with Altera Development boards and Terasic DE3 host boards.
  • External Clock In / Out Interface
  • Two 14-bit Analog to Digital (A/D) converter channel with 150MSPS
  • Two 14-bit Digital to Analog (D/A) converter channel with 250MSPS
  • One Audio CODEC with Line-In, Line-Out, MIC and Headphone
  • Size :145mm x 80mm x 18mm (L x W x H)

Transmission Demo

The AD/DA Data Conversion CD includes a reference design which contains two sine waves that are generated by two instances of the Altera numerically controlled oscillator (NCO) MegaCore. One of these oscillators is running at 10 times the frequency of the other, but both of them have the same amplitude with each one covering 13 bits of dynamic range. From these blocks, the two sine waves output are converted from two’s complement binary to unsigned binary format which then are added together. The combined sine wave signal of 14-bits dynamic range is sent to a 14-bit D/A converter. The analog output of a D/A converter is connected via SMA Cable with the analog input of a 14-bit A/D converter. The A/D converter’s digital output is looped back to the FPGA device. The A/D is configured by the dip switches to deliver the data in unsigned format. The converted loopback data is captured by an instance of the SignalTap® II logic analyzer in the design for display and analysis.

The following figure below shows a high-level view of the reference design and how it interacts with the D/A and A/D converters on the AD/DA Data Conversion Card in the following sections.

You can use MATLAB software to analyze the data. 
The following figure below is generated using SignalTap to capture and analyze data.

The package of the AD/DA Data Conversion Card includes

  • One AD/DA Data Conversion Card
  • One System CD
  • One Accessories package (screw、standoff、Jumper)
