GENERAL DESCRIPTION
The W83195R-08 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel Pentium II. W83195R-08 provides sixteen CPU/PCI frequencies which are externally selectable with smooth transitions. W83195R-08 also provides 17 SDRAM clocks controlled by the none-delay buffer_in pin.

PRODUCT FEATURES
●  Supports PentiumÔ II CPU with I2C.
●  3 CPU clocks (one free-running CPU clock)
●  17 SDRAM clocks for 4 DIMs
●  7 PCI synchronous clocks
●  Two IOAPIC clocks for multiprocessor support
●  Optional single or mixed supply:
   (Vddq1=Vddq2 = Vddq3 = Vddq4 = VddL1 =VddL2= 3.3V) or (Vddq1= Vddq2 = Vddq3=Vddq4 =
   3.3V, VddL1 = VdqL2 = 2.5V)
●  < 250ps skew among CPU and SDRAM clocks
●  < 250ps skew among PCI clocks
●  < 5ns propagation delay SDRAM from buffer input
●  Skew from CPU(earlier) to PCI clock -1 to 4ns, center 2.6ns.
●  Smooth frequency switch with selections from 50 MHz to 133 MHz CPU
●  I2C 2-Wire serial interface and I2C read back
●  ¡Ó0.25% or ¡Ó0.5% center type spread spectrum function to reduce EMI
●  Programmable registers to enable/stop each output and select modes
   (mode as Tri-state or Normal )
●  MODE pin for power Management
●  One 48 MHz for USB & one 24 MHz for super I/O
●  56-pin SSOP package
