.
33-KHz triangular modulation is required along with other spread amounts and modulation
algorithms, such as a maximum of 50 kHz
f/
t modulation, are left up to the clock generator
vendor to include as differentiating features.

Skew
Skew for AMD64 processor-based systems must be specified in two ways.
Time Independent Skew:
The allowable skew between clock outputs that does not vary over
time (not dependent upon voltage or temperature changes or co-related with other outputs due to
voltage and temperature changes).
Time Variant Skew:
The allowable skew between clock outputs that vary over time (with
changes in voltage and temperature and that does not effect processor, HT66, or PCI33 outputs
equally). The requirement for the time variant specification is derived directly from the
HyperTransport technology consortium source point.
Table 15 shows the skew characteristics for the AMD64 processor-based systems.
