The W83194BR-39B is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel Pentium II or Pentium III. W83194BR-39B provides 64 CPU/PCI frequencies which are selectable with smooth transitions by hardware or software. W83194BR-39B also provides 13 SDRAM clocks controlled by the none-delay buffer_in pin..

CPU with I2C. 2 CPU clocks (one free-running CPU clock) 13 SDRAM clocks for 3 DIMMs 6 PCI synchronous clocks One IOAPIC clock for multiprocessor support Optional single or mixed supply: (Vddq1=Vddq2 = Vddq3 = Vddq4 = VddL1 =VddL2= 3.3V) or (Vddq1= Vddq2 = Vddq3=Vddq4 = 3.3V, VddL1 = VddL2 = 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 66 MHz to 200 MHz CPU Step-less frequ.
