FMC230: How To Operate In The Second Nyquist Zone?
started a topic
over 7 years ago
For our application we would like to operate the FMC230 DAC in the second Nyquist zone. We are seeing 39 dB of attenuation in the Second Nyquist Zone on the FMC230 when compared to the First Nyquist Zone. That is too much for our application.
How do we reduce the attenuation in the second Nyquist zone?
Test Setup: - External Clock = 1333.333333 MHz - DAC digital input is a single sine wave at 100 MHz
There is another forum thread that might be related titled "Unexpected Amplitude Transfer from FMC230" but I was not able to access it because it was moved to another forum for which I don't have access. Your help is appreciated.
