Hi Amit, That's correct, assuming you are operating the adc in single input mode. It also has a dual-input mode, where the first 8 outputs are one input, and the second 8 are the other. Don't forget that the input clock in single input (aka interleaved) mode should be half the total sample rate.

[casper] ASIAA adc5g downsampling

Hello, We are trying to sample a signal 100 MHz to 270 MHz with fpga running at 250MHz. To downsample by 4, I simply take every 4th output of the 16 outputs available from the yellow block of asiaa adc5g. We do have an anti-aliasing filter for the desired 500MHz bw. Is this correct or am I
