W83194R-17 - 100MHZ AGP CLOCK FOR SIS CHIPSET

Description

The W83194R-17/-17A is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumII, PentiumPro , AMD or Cyrix.

Eight different frequency of CPU, AGP and PCI clocks are externally selectable with smooth transitions.

Features

  • Supports Pentium™, Pentium™ Pro, Pentium™ II, AMD and Cyrix CPUs with I2C. 4 CPU clocks 12 SDRAM clocks for 3 DIMMs Two AGP clocks 6 PCI synchronous clocks. Optional single or mixed supply: (Vdd = Vddq3 = Vddq2 = Vddq2b = 3.3V) or (Vdd =Vddq2 = Vddq3 = 3.3V, Vddq2b = 2.5V) Skew form CPU to PCI clock -1 to 4 ns, center 2.6 ns, AGP to CPU sync. skew.

W83194R-17/-17A 100MHZ AGP CLOCK FOR SIS CHIPSET 1.0 GENERAL DESCRIPTION The W83194R-17/-17A is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumII, PentiumPro , AMD or Cyrix. Eight different frequency of CPU, AGP and PCI clocks are externally selectable with smooth transitions. The W83194R-17/-17A provides AGP clocks especially for clone chipset. The highest CPU frequency provided by the W83194R-17 is up to 100MHz, but the one of W83194R-17A is up to 133MHz. The W83193R-17/-17A provides I2C serial bus interface to program the registers to enable or disable each clock outputs and choose the 0.5% or 1.5% center type spread spectrum to reduce EMI. The W83194R-17/-17A accepts a 14.
