GENERAL DESCRIPTION
The W83194BR-730 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as AMD K7. W83194BR-730 provides 64 CPU/PCI frequencies which are selectable with smooth transitions by hardware or software. W83194BR-730 also provides 13 SDRAM clocks.

PRODUCT FEATURES
• Supports AMD CPU with I2C.
• 3 CPU clocks (one free-running CPU clock)
• 13 SDRAM clocks for 3 DIMMs
• 6 PCI synchronous clocks
• 2 AGP clocks
• 2 REF clocks as 14.318MHz outputs
• < 250ps skew among CPU and SDRAM clocks
