I'm using TM4C129xx that includes ETHERNET MAC & PHY.The cryastal that is in use is 25MHZ.

If I select the crystal for being the ADC clock input thus it mean that the ADC conversion rate is 1.56Msps?

Hi Avi,

On TM4C129xx If you select crystal for ADC Clock then conversion rate is 1.56MSPS. However we have not completed the characterization for the ADC at clock more than 16MHz. So ADC converted data may not be correct.
