 GENERAL DESCRIPTION
The W83194BR-C is a Clock Synthesizer for Intel Camino 820 chipset. W83194BR-C provides all clocks required for high-speed RISC or CISC microprocessor and also provides 64 different frequencies of CPU, PCI, 3V66, IOAPIC clocks frequency setting. All clocks are externally selectable with smooth transitions.

PRODUCT FEATURES
• 2 CPU clock outputs
• One CPU/2 output as reference input to DRCG
• 3 3V66 clock outputs
• 3 IOAPIC clock outputs
• 8 PCI synchronous clocks.
• Optional single or mixed supply: (VddQ2 = VddQ3 = 3.3V or VddQ3=3.3V, VddQ2=2.5V)
• CPU to 3V66 offset .0 to 1.5 ns
• 3V66 to PCI offset 1.5 to 4.0 ns
• Skew form CPU to PCI clock 1 to 4 ns, center 2.6 ns
• Smooth frequency switch with selections from 66.8 to 200MHz
• I2C 2-Wire serial interface and I2C read back
• 0.5% and 0.75% center type spread spectrum
• Programmable registers to enable/stop each output and select modes (mode as Tri-state or Normal )
• 48 MHz pins for USB
• 24 MHz for super I/O
• 48-pin SSOP package
