W83194R-39A - 100MHZ 3-DIMM CLOCK

General Description

The W83194R-39/-39A is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel Pentium II.

Key Features

  • Supports Pentium™ II CPU with I2C.
  • 2 CPU clocks (one free-running CPU clock).
  • 13 SDRAM clocks for 3 DIMs.
  • 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 = VdqL2 = 2.5V).
  • < 250ps skew among CPU and SDRAM clocks.
  • < 250ps skew among PCI clocks.
  • < 5ns propagation dela.

W83194R-39/-39A 100MHZ 3-DIMM CLOCK 1.0 GENERAL DESCRIPTION The W83194R-39/-39A is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel Pentium II. W83194R-39 provides eight different frequency of CPU and PCI clocks and W83194R-39A provides sixteen CPU/PCI frequencies which are externally selectable with smooth transitions. W83194R-39/-39A also provides 13 SDRAM clocks controlled by the none-delay buffer_in pin. The W83194R-39/-39A accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply. Spread spectrum built in at ¡Ó0.5% or ¡Ó0.25% to reduce EMI. Programmable stopping individual clock outputs and frequency selection through I2C interface.
