Description
The W83194R-630A is a Clock Synthesizer for SiS 540/630 chipset. It provides all clocks required for high-speed RISC or CISC microprocessor such as AMD, Cyrix, Intel Pentium, Pentium II. It also offers 16 different frequencies of CPU clocks frequency setting. All clocks are externally selectable with smooth transitions. The W83194R-630A makes SDRAM in synchronous or asynchronous frequency with CPU clocks. It provides I2C serial bus interface to program the registers to enable or disable each clock outputs. The W83194R-630A also provides the 0.5%, 0.75% center type and 0~0.5% down type spread spectrum to reduce EMI.
