interleave two ad9288 to cyclone iii

Altera_Forum · ‎05-17-2012

I wish to connect two AD9288 (fast ADC) with interleave method , four clocks with 90 degree phase shift of 125MHz are connected to two AD9288 , their output are passed to cyclone iii FPGA for processing , so I ask if this equivalent to 500MHz signal input to cyclone iii ?? can they handled this fast I/O signal ???

What the FPGA will have as inputs will be 4 separate bus, each 8 bit wide and operating at 125 MHz.

That, it can handle.

Now.. if you want to interleave the data from the 4 channels inside the FPGA then it depends on how you'll do it.

Do you really need to handle the data stream using 8 bit wide, 500 MHz logic blocks?

That's pretty much NOT possible.

Or can you parallelize your processing and the clock, ie handle 32 bit wide vectors and use only a 125 MHz clock?
