Source-Synchronous Switching Characteristics
The parameters in this section provide the necessary values for calculating timing budgets for Virtex-II Pro
source-synchronous transmitter and receiver data-valid windows.
Table 61: Duty Cycle Distortion and Clock-Tree Skew
DS083 (v4.7) November 5, 2007
Product Specification
Notes:
1. These parameters represent the worst-case duty cycle distortion observable at the pins of the device using LVDS output buffers. For
2. This value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew
Duty Cycle Distortion
Clock Tree Skew
cases where other I/O standards are used, IBIS can be used to calculate any additional duty cycle distortion that might be caused by
asymmetrical rise/fall times.

applies to cases where the dedicated path from the DCM to the BUFG is bypassed and where local (IOB) inversion is
for these specifications to apply.
applies to cases where the CLK180 output of the DCM is used to provide the negative-edge clock to the DDR element
