Regarding AD7656 interfacing Cyclone-IV FPGA

Question asked by Nandish on Feb 5, 2013

Hi,

 

   I used AD7656, whose supplies are as follows:

 

AVCC = 5V (Analog Supply)

DVCC = 5V (Digital Supply)

VDrive = 3.3V (Digital Supply)

VDD = +15V (Analog Supply)

VSS = -15V (Analog Supply)

 

    Is it possible to interface AD7656 directly with EP4CE55 FPGA (Cyclone-IV, Altera), without using voltage translator (SN74ALVC164245)?\

 

Regards,

Nandish
