1. GENERAL DESCRIPTION
The W83195CW-NP is a CK410M compliant Clock Synthesizer for Intel P4 processors. W83195CW-
NP provides all clocks required for high-speed microprocessor and provides, 8 different frequencies of
CPU, PCI, PCI-Express clocks setting. Simultaneously W83195CW-NP supports DOT 96MHz clock
outputs for integrated graphic chipsets. All clocks are externally selectable with smooth transitions.
The W83195CW-NP programs the registers to enable or disable each clock outputs through I2C serial
bus interface and provides -0.5% spread spectrum or programmable spread spectrum scale to reduce
EMI.
The W83195CW-NP is driven with a 14.318 MHz reference crystal and runs on a 3.3V supply.
