Additional features of the system clock are as follows:
3.3-V operation
Two true differential processor clocks pairs (supports both 1P and 2P platforms)
Seven 3.3-V dedicated 33-MHz PCI clocks, one free-running
Three 3.3-V selectable 66-MHz or 33 MHz clocks to be used for HyperTransport
technology reference clocks or PCI 33-MHz clocks
One 3.3-V 48-MHz output for USB
One 3.3-V 24-MHz or 48-MHz for SIO
Three 3.3-V 14.318-MHz reference clocks (one additional to provide reference to external
24.576 MHz generator if needed for AC97 codecs)
EMI Suppression using spread spectrum technology (down spread only with 33 kHz triangular
modulation)
SMbus interface for configuration register programming and read back (Rev 1.0)
Power management control inputs
