FPGA with built-in ADC

[Altera_Forum]

Hi, 

 Any one would provide me with a datasheet of any FPGA that has built-in ADC. Also what is the maximum speed and resolution that are available in any FPGA with internal ADC?  Thanks

IIRC, no Altera FPGA has a built-in ADC. 

 Actel has some FPGA with built-in low speed ADCs. Xilinx also has built-in ADC in the 7 families, up to 12 bits and 1 Msamples/s.  Some people have designed FGPA based ADCs, either using sigma delta or Wilkinson converters.

I believe there is no built_in ADC with the requirements I need. it is 8-bit resolution, 36MSPS. I just want to see what kind of ADC they have and how they implemented it. Im trying to implement my own digital ADC. 

 Thanks for the info...

Analog Devices and Texas Instruments will have plenty of devices that meet these specifications.  Why try to implement your own? What are you trying to learn?  Cheers, Dave
