One 2.5V IOAPIC clock.
Two14.318MHz reference clocks.
Power management control to stop CPU, PCI,
SDRAM and IOAPIC clocks.
Support 2-wire I2C serial bus interface with built-
in Vendor ID, Device ID and Revision ID.
Single byte micro-step linear Frequency
Programming via I2C with Glitch free smooth
switching.
Spread Spectrum 0.25% center.
50% duty cycle with low jitter.
Available in 300 mil 48 pin SSOP.
