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. This table assumes the following
parasitic factors: combined PCB trace and land inductance per
V
Test limits are the V
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.
