Hi Uttara
No behavioral models (spice or other formats) are available for the ADS42JB69.
We do have IBIS models available to verify signal quality of the digital I/O. Those are available here:
http://www.ti.com/product/ADS42JB69/toolssoftware#simulationmodels
We also have an Application Report which discusses how to correct the low-frequency response of the converter. That is available here:

I hope this is helpful.
Best regards,

Hi Uttara
I'll see if there is anything else we can provide.
Can you describe what you are trying to confirm regarding SYSREF?
Is it related to the timing between SYSREF and CLKIN, or some other detail?
Best regards,
Jim B
Uttara,
The signal Mark should have been describing above is SYSREF, not SYNC. Attached is the IBIS model for this device and another document showing an example of how to drive the SYNC and SYSREF signals.
Regards,
Jim
