GENERAL DESCRIPTION
The W83194BR-S is a Clock Synthesizer for Intel 815 Solano chipset. W83194BR-S provides all clocks required for high-speed RISC or CISC microprocessor and also provides 64 different frequencies of CPU, SDRAM, PCI, 3V66, IOAPIC clocks frequency setting. All clocks are externally selectable with smooth transitions.

PRODUCT FEATURES
