W83194R-58A - 100MHZ AGP CLOCK FOR VIA CHIPSET

General Description

The W83194R-58A is a Clock Synthesizer for VIA chipset.

W83194R-58A provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumII and also provides 16 different frequencies of CPU clocks by software setting.

Key Features

  • Supports Pentium™, Pentium™ Pro, Pentium™ II, AMD and Cyrix CPUs with I2C. 4 CPU clocks 12 SDRAM clocks for 3 DIMs Two AGP clocks 6 PCI synchronous clocks. Optional single or mixed supply: (Vdd = Vddq3 = Vddq2 = Vddq2b = 3.3V) or (Vdd = Vddq3 = Vddq2 = 3.3V, Vdq2b = 2.5V) Skew form CPU to PCI clock -1 to 4 ns, center 2.6 ns, AGP to CPU sy.

W83194R-58A 100MHZ AGP CLOCK FOR VIA CHIPSET 1.0 GENERAL DESCRIPTION The W83194R-58A is a Clock Synthesizer for VIA chipset. W83194R-58A provides all clocks required for high-speed RISC or CISC microprocessor such as Intel PentiumII and also provides 16 different frequencies of CPU clocks by software setting. AGP and PCI clocks are externally selectable with smooth transitions. The W83194R-58A provides AGP clocks especially for clone chipset, and makes SDRAM in synchronous frequency with CPU or AGP clocks. The W83194R-58A provides I2C serial bus interface to program the registers to enable or disable each clock outputs and choose the 0.25%, 0.5% or 0.5%,1.5% center type spread spectrum to reduce EMI. The W83194R-58A accepts a 14.318 MHz reference crystal as its input and runs on a 3.
