Spartan DSP 3400 interfacing ro TI ADC-ADS6144--debug issue

we have designed a board based on spartan DSP 3400. our board has TI-ADS6144, TI ADC has SPI control interface,

through which we programmed for test patterns ,we got all the expected results.

but

when we actually feed the analog signal and plot the data in the buffer we are not getting the input signal wave form shape.

we are using EDK tool and chip scope. ADC is operated at 96Mhz and input signal is 2Vp-p with 10Mhz sine wave,

 

looking for valuable suggestions to correct the same
