In troubleshooting system EMI issues, a large emmision around 196 MHz is noted from the ADC128D818. This can be seen at initial power up without any specific data transmissions. The device is in default power up mode, which it is assumed the ADC is not sampling.
There is no informaiton in the data sheet about the internal clocks.Could this 196 MHz issue be from the internal ADC clocks? Is there any way to reduce EMI emmissions?
