Open ADC input specifications

Hello,

I got the openADC chip to integrate with the Altera DE2 board, to implement a portable oscilloscope. I have some questions on the test setup. What are the minimum and max( voltage, frequency) that I could use on the LNA input. Do you have any timing diagrams that I could refer to, to see what the output at the trigger input to the FPGA, clock input to the FPGA and the ADC outputs would look like for a given input?

Thanks!
