AD9680 SNR using AD-FMCDAQ2-EBZ

Hi,

1.

We recently purchased the AD-FMCDAQ2-EBZ along with Kintex platform.

I was going through the documentation in the AD Wiki site and came across the Receive specifications in the page given below:

https://wiki.analog.com/resources/eval/user-guides/ad-fmcdaq2-ebz/hardware/card_specification

The last graph is labelled as "SFDR sweep compared to Eval board with AD9523-1 reference clock".

Please clarify this point.

I believe that all the graphs shown are created with on-board AD9523-1 clock synthesiser.

2.

I simulated the AD9523-1 in ADISIMClk and obtained a jitter of 220fs at 1GHz LVPECL output.

This is the worst jitter specification given in the Fig139 of datasheet.

Is there a better clock synthesizer available which can achieve a lower jitter specification.

Regards,

Vishnu R.
