W161 133-MHz Spread Spectrum FTG

W161 CPU Clock Outputs 0 through 2: CPU clock outputs. Their output voltage swing is controlled by voltage applied to VDDQ2. PCI Clock Outputs 0 through 9: Output voltage swing is controlled by voltage applied to VDDQ3. CPU-Divide-By-2 Output: This serves as a reference input signal for Direct Ram.
