AMCC Proprietary
Revision 1.23 - Sept 21, 2006
Preliminary Data Sheet
For PCI-X and PCI 66 the maximum spread spectrum is -1% modulated between 30kHz and 33kHz.
For PCI Express, the maximum spread spectrum is
-0.5%,
modulated between 30kHz and 33kHz. The ports
on the two ends of a link must transmit data at a rate that is within 600 parts per million (ppm) of each other at
all times. This is specified to allow bit rate clock sources with a +/- 300 ppm tolerance.
Notes:
1. The serial port baud rates are synchronous to the modulated clock. The serial port has a tolerance of
approximately 1.5% on baud rate before framing errors begin to occur. The 1.5% tolerance assumes that
the connected device is running at precise baud rates.
2. Ethernet operation is unaffected.
3. IIC operation is unaffected.
Important:
It is up to the system designer to ensure that any SSCG used with the PPC440SPe meets the above
requirements and does not adversely affect other aspects of the system.
