W83116WG pdf Datasheet(V11 Low Power Clock Gen for Intel CK50

The W83116WG-511 is a low power clock synthesizer for Intel CK505 compatible platform, which has low power differential outputs, an integrated Voltage regulator, as well as an integrated 33Ω series resistor. It also provides all of the clocks required for the high-speed microprocessor, and step-less frequency programming.
The W83116WG-511 supports 32 different frequencies of CPU, PCI, PCIEX clock setting, as well as SATA and DOT clock outputs. All clocks are externally selectable with smooth transitions.
Programming the registers through I2C serial bus interface can enable or disable each clock output, reduce EMI by -0.5% down type spread spectrum or programmable S.S.T. scale. Dynamic overclocking is also available.
The W83116WG-511 accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V power supply.
