CCAUX
Not all I/O standards are supported on all I/O banks. The left and
right banks (I/O banks 1 and 3) support higher output drive
current than the top and bottom banks (I/O banks 0 and 2).
Similarly, true differential output standards, such as LVDS, RSDS,
PPDS, miniLVDS, and TMDS, are only supported in top or bottom
banks (I/O banks 0 and 2). Refer to UG331: Spartan-3
Generation FPGA User Guide for additional information.
The numbers in this table are recommendations that assume
sound board lay out practice. Test limits are the V
limits for the respective I/O standard.
If more than one signal standard is assigned to the I/Os of a given
bank, refer to XAPP689: Managing Ground Bounce in Large
FPGAs for information on how to perform weighted average SSO
calculations.
