W83194BR-KT General Description
The W83194BR-KT is a Clock Synthesizer which provides all clocks required for AMD K7.
W83194BR-KT provides 64 CPU/PCI frequencies which are selectable with smooth transitions by hardware or software.
W83194BR-KT also provides 13 SDRAM clocks controlled by the none-delay buffer_in pin.
The W83194BR-KT provides step-less frequency programming by controlling the VCO freq. and the programmable PCI clock output divisor ratio. A watchdog timer is quipped and when time out, the RESET# pin will output 4ms pulse signal.
The W83194BR-KT accepts a 14.318 MHz reference crystal as its input. Spread spectrum built in at ±0.5% or ±0.25% to reduce EMI. Programmable stopping individual clock outputs and frequency selection through I2C interface. The device meets the Pentium power-up stabilization, which requires CPU and PCI clocks be stable within 2 ms after power-up. Using dual function pin for the slots (ISA, PCI, CPU, DIMM) is not recommend.
