DAC with THDB-ADA on DE2-115

Hi tan,

I am currently creating a spread-sheet for the pin assignments. Well thanks a lot! i'll verify my assignments with what you have sent. I have another doubt,

The ADA board feature list mentions the following:

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

The entire board operates on DC-signaling if am not wrong, as our board is powered by an adapter. So what does it exactly mean by

DA and AD converters do not support DC signalling?

Also i think there is a mistake in the pins wrt_a and wrt_b as there is no pin such as T24 and W25 available.

Am attaching the schematics of Cyclone 3 Starter Board for your reference.

thanks!
