Applying ADC on DE1

[Altera_Forum]

I just ordered a DE1 design kit and I want to applay analog to digital converter on the board. 

1. There are 4 VGA ADCs. They can be used as regular ADCs? 
2. Can someone send me a link or mail with the DE1 user manual?

Thanks, Very bigginer :-)

This is the link of the DE1 Manual (anyway you'll find it on the dvd provided with the board) 

 http://www.innovatenordic.com/download/document/de1_usermanual_v1018.pdf  There aren't VGA ADCs but DACs (4bit resistor network as you can read on the manual). If you want an ADCs you need to apply it by yourself (on the Terasic website you can find some useful AD/DA card) I hoe I was of help to you.  GP

Thank you for the fast replay. 

I was wrong with the VGA DAC; I need ADC.   I've read about a sigma delta ADC applying by FPGA, very interesting! (attached link at the end).  Do you familiar with this concept? Can it be applied on the DE1?  Regards Eyal   http://www.alteraforum.com/forum/showthread.php?p=775&posted=1#post775  or searched the threads for: "ADC with Stratix and NIOSII" (May 8th, 2007) by Daniel.

Sorry I'm just a beginner so I can't be helpful to you. Anyway Cyclone II (it's placed on the DE1 board right?) support LVDS signals so I think it's possible to use LVDS as ADCs as described in the link you gave me.  

 you can find more infos about sigmadelta on wikipedia: http://en.wikipedia.org/wiki/delta-sigma_modulation  or try this tutorial by analog device:  http://www.analog.com/static/imported-files/tutorials/mt-022.pdf  http://www.analog.com/static/imported-files/tutorials/mt-023.pdf   because of I'm interested in applying a ADC to my board (DE0) too, if you can get results, can you share with me? :)  regards GP

Thanks, GP. 

 I'll review it in the weekend.  Eyal.
