Hi,
I am trying to implement FIR MegaCore in my design, but I got confused about a parameter in the Mega Wizard. If I am using the interpolation feature, with a factor of 8, does that mean the input sample rate (in the next pane) is the original data input rate * interpolation factor? or I just input the original data rate? For example: My original input rate is 175 Kbps, and I want to upsample the input by 8 then filter it, do I enter 175 Kbps as input sample rate? or I enter 175 Kbps * 8 = 1.4 Mbps?Link Copied

Thanks kaz, yes clock rate is in the same pane, mine is 50 MHz. I was just confused about input sample rate.
