ADC Evaluation Board:HSC-ADC-EVALCZ Frontend ADC: AD6657 Clock Input: Sine Wave (Low Jitter) 200 MHz 10 dBm The Captured Data by this EVAL Board not generating the Captured Sine Wave. Seems to be missing a lot of intermediate samples.

ADC Evaluation Board:HSC-ADC-EVALCZ
Frontend ADC: AD6657
Clock Input: Sine Wave (Low Jitter) 200 MHz 10 dBm

The purpose of my work is to capture the Digital Data from a Agilent Analog Signal Generator and save it to CSV file.
Analog Input Frequency (applied to AIN B/J303): 10 MHz 12-19 dBm Sine Wave
Problem I am facing is that, the data is all positive values of form 32XXX (X is from 0-9). The sign wave representable by the captured values (captured using VisualAnalog) seems jagged and not at all a continuous Sine Wave.

I have kept the necessary files at the link:
gudduarnav.com/.../

The files named new*.csv are data saved in time domain.

The *.vac files are the VisualAnalog files designed for the purpose.

The Image at:
gudduarnav.com/.../SampleImagefromCapturedData1.jpg
shows the Sine wave which can be seen from the captured data. The wave is not smooth and seems to miss a lot of intermediate sample.

The Hardware Setup image links are:

Kindly assist me in rectifying what I am doing wrong.Thanks in advance.
