W83194R-81 Datasheet 100mhz Clock For Sis Chipset

Manufacturer: Winbond

Overview: W83194R-81 100MHZ CLOCK FOR SIS CHIPSET 1.0 GENERAL.

General Description

The W83194R-81 is a Clock Synthesizer for SiS chipset.

W83194R-81 provides all clocks required for high-speed RISC or CISC microprocessor such as AMD,Cyrix,Intel Pentium and also provides 16 different frequencies of CPU clocks frequency setting.

All clocks are externally selectable with smooth transitions.

Key Features

  • Supports Pentium™, Pentium™ Pro, AMD and Cyrix CPUs with I2C. 3 CPU clocks 13 SDRAM clocks for 3 DIMMs 6 PCI synchronous clocks. Optional single or mixed supply: (Vdd = Vddq4=Vddq3 = Vddq2b = 3.3V, Vddq2=2.5V) or (Vdd = Vddq4=Vddq3 = 3.3V, Vddq2=Vdq2b = 2.5V) Skew form CPU to PCI clock -1 to 4 ns, center 2.6 ns SDRAM frequency synchronous or asynchronous to CPU clocks Smooth frequency switch with selections from 66 to 133mhz(including 90MHz) I2C.
