Hi,
I use a 80MgHz sine wave signal as ADS5204 clock which coming from signal generator to transformer (1:4 for signal amplify) and connecting the positive end of the 2nd coil of transformer to provide clock for ADS5204 while negative end of 2nd coil connecting to ground .
After that, I see all of other pins have a small (about 30% of clock amplitude) 80MgHz signal on its DC level.
Can you please tell me which connection is wrong and why it caused a problem like this.
Thank you.
