PI6C03

The PI6C133, a low-skew, low-jitter 133 MHz clock generator ,is specifically designed to meet all the clocking requirements for 133 MHz and 100 MHz desktops with high-performance and lower-power features.

Split power supplies of 2.5V and 3.3V are used to reduce power consumption, minimize noise and to ensure CPU independence. The 2.5V supply is used to power CPUCLK clocks to the PI6C133 processor module. 2.5V signalling is compliant to JEDEC standard 8-X. The rest of the circuitry is powered by a 3.3V supply.

Key features of PI6C133, such as power-management and spread-spectrum functions, are fully supported. PWRDWN# signal will turn off all internal circuits and keep all outputs to a low state, making the power consumption less than 100mA. For less stringent power requirements, CPUSTOP# will turn off CPUCLK and 3V66 outputs instantaneously. Spread spectrum function can be optionally disabled by pulling SPREAD# pin to a HIGH state.
