Product Specification
42
The capacitive load (CL) is connected between the output
and GND. The Output timing for all standards, as published
in the speed files and the data sheet, is always based on a
CL value of zero. High-impedance probes (less than 1 pF)
are used for all measurements. Any delay that the test
fixture might contribute to test measurements is subtracted
from those measurements to produce the final timing
numbers as published in the speed files and data sheet.

Notes:
1.
Descriptions of the relevant symbols are as follows:
VREF – The reference voltage for setting the input switching threshold
VICM – The common mode input voltage
VM – Voltage of measurement point on signal transition
VL – Low-level test voltage at Input pin
VH – High-level test voltage at Input pin
RT – Effective termination resistance, which takes on a value of 1 M when no parallel termination is required
VT – Termination voltage
2.
The load capacitance (CL) at the Output pin is 0 pF for all signal standards.
3.
According to the PCI specification. For information on PCI IP solutions, see
www.xilinx.com/products/design_resources/conn_central/protocols/pci_pcix.htm. The PCIX IOSTANDARD is available and has equivalent
characteristics but no PCI-X IP is supported.
