Notes:
1. The numbers in this table are based on the conditions set forth in
Table 77 and Table 80.

2. Descriptions of the symbols used in this table are as follows:
12

–12
IOL – the output current condition under which VOL is tested
IOH – the output current condition under which VOH is tested
VOL – the output voltage that indicates a Low logic level
VOH – the output voltage that indicates a High logic level
VCCO – the supply voltage for output drivers
VTT – the voltage applied to a resistor termination
3. For the LVCMOS and LVTTL standards: the same V and V
OL
OH
limits apply for both the Fast and Slow slew attributes.
4. Tested according to the relevant PCI specifications. For
information on PCI IP solutions, see www.xilinx.com/pci. The
PCIX IOSTANDARD is available and has equivalent
characteristics but no PCI-X IP is supported.
