Hi,=20
I used Virtex4 from Xilinx and there were Class I and II for SSTL_1.8. =
The datasheet list the different configuration of SSTL_18 and SSTL2 =
Class.
For bidirectionnal interface, I don't think there are drive =
differences. The datasheet Xilinx says to use ClassI for =
unidirectionnal and ClassII for bidirectionnal, that's all.
Regards
Alexandre

Objet : [SI-LIST] why no class-I/II in SSTL_1.8
Hi,
Are there any ClassI/II type of interfaces in SSTL_1.8. I could see =
in SSTL_2 there are class-I and II interfaces for unidirectional and =
bidirectional signalling.=20
For bidirectional interface in SSTL_1.8 are there any current drive =
differences, like in SSTL2, 8.1mA for Class-I and 16.2mA for class-II.
