ADC08DJ3200EVM: How to use FPGA capture the data from ADC08DJ3200EVM ?

Part Number: ADC08DJ3200EVM

Hi,

      I bought a ADC08DJ3200EVM , and I want to use the FPGA board designed by myself to capture the data from ADC08DJ3200EVM . The input data is sine wave with 300MHz 200mV. I select Fs =1000 MHz MSPS as the onboard Fs selection and JMODE4 for the decimation and serial data mode. But the data I captured from the ADC is wrong and it is shown as the picrure below. Could you help me find the problem ?
