W83194R-17/-17A is a clock synthesizer
General description
W83194R-17 /-17A is a clock synthesizer, which provides all clocks or CISC microprocessors required by high-speed RISC, such AMD or Cyrix. The frequency of eight different CPUs, AGPs and PCI clocks can be selected from the outside through smooth conversion. This W83194R-17/-17A provides an AGP clock, especially the clone chipset. The highest CPU frequency W83194R-17 provides a frequency of 100MHz, while the frequency provided by W83194R-17A is as high as 133MHz.
W83193R-17/-17A provides the I2C serial bus interface, programming the register to enable or disable each clock output and select 0.5%or 1.5%central expansion to reduce electromagnetic interference.
W83194R-17/-17A accepts 14.318MHz reference crystals as input and runs under 3.3V voltage. High -drive PCI and SDRAM clock output usually provide a conversion rate greater than 1V/NS to install 30 PF loads. The CPU clock output usually provides a working cycle of 50-5%of the conversion rate better than 1V/NS to 20PF load. The fixed frequency output provides a conversion rate better than 0.5V/NS for REF, 24MHz and 48MHz.
