Following up on the post:
I see that the ADC is capable of 640MSPS operation, and from the datasheet, I see that the Rx channel bandwidth is tunable up to 56MHz.
Q1: is this a dual-320MSPS 12-bit ADC?
Q2: What is limiting the available channel bandwidth?
Q3: Is it possible to utilize the full 640MSPS as a "bare" ADC (perhaps bypassing the FIR, and perhaps as a single channel)? If not, what is the maximum sample rate that can be captured from this device?
The FMCOMMS3-EBZ board was delivered with a startup SDHC card containing a version of the oscilloscope program "osc", but this appears to limit the allowable sample rate for either channel. Depending on the answer to my questions Q1 - Q3, could I modify this code to capture the highest possible sample rate (for a single channel)? I am using it on a ZC702 board, and I have been using the FMCOMMS1-EBZ board on this same setup (at up to 245.76MHz I/Q sample rate for the AD9643 ADC) with a different version of "osc", thus displaying a total bandwidth of 245.76MHz.
