AFE5807EVM: External ADC sampling rate can be higher like 80 MHz?

We want to use this evaluation board to receive data from a high-frequency transducer (central frequency: ~30MHz), the highest sampling rate for the IC can be 80MHz, but the onboard clock is only 40 MHz. We saw they have external ADC clock, can we input for example 80MHz to external ADC clock? Thank you!
