DE2i-150 - HSMC THDB-ADA Daughter Card (Analog to Digital Converter)

Hi ,

In the ADA feature it specifies that the board has clock source of 100 Mhz . The pdf has been attached for reference!

The feature set of the ADA is listed below:

1. Dual AD channels with 14-bit resolution and data rate up to 65 MSPS

2. Dual DA channels with 14-bit resolution and data rate up to 125 MSPS

3. Dual interfaces include HSMC and GPIO, which are fully compatible with Cyclone III Starter

Kit and DE1/DE2/DE2_70/DE2_115/DE3/DE4, respectively

4. Clock sources include oscillator 100MHz, SMA for AD and DA each, and PLL from either

HSMC or GPIO interface

5. AD converter analog input range 2V p-p range.

6. DA converter output voltage range 2V p-p range.

7. DA and AD converters do not support DC signaling

So does it imply the board has its own clock? if so how do we enable it?

Thanks!
