GENERAL DESCRIPTION

The W83195BR/G-101 is a Clock Synthesizer for Intel P4 processors and Intel Grandsdale chipsets. W83195BR/G-101 provides all clocks required for high-speed microprocessor and provides step-less frequency programming, 32 different frequencies of CPU, PCI, SRC clocks setting. Simultaneously W83194BR-101 supports SRC_SATA 100MHz clock output for SATA and DOT 96MHz clock outputs for integrated graphic chipsets. All clocks are externally selectable with smooth transitions.
