W83196S-14 Description
The W83196S-14 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor. Twelve different frequency of CPU, and PCI clocks are externally selectable with smooth transitions. The W83196S-14 provides I2C serial bus interface to program the registers to enable or disable each clock outputs and choose the 0.5% center type spread spectrum to reduce EMI.
