vc707 AW32 pin IOSTANDARD problem

Jump to solution

vc707 user guide has metioned that AW32 and AW33 (page 88) have IOSTANDARD as LVCOMS18. But when i used OBUFDS to supply a clk to those pin, implementation statge will give error mentioning that those pin are differential. when i used IOSTANDARD as LVDS, it is ok.

 

can anyone give me the reason to this issue?

thanks pratham

 

this is not related to IOSTANDARD but it also can be a typo.

 

ug885 (v1.5) in page 49 has mentioned that slave address of si5324 as 0b1010000. but in ug885 (v1.6.1) in page 49 has mentioned that slave address of si5324 as 0b1101000.

 

what is the correct slave address?

 

PS:- ug885 (user guide of vc707)

@allien It was wrong in 1.5 version of  the UG. We got this fixed in version 1.6.1.

 

Always refer newer version of the document to get the correct information.
