Additional preview pages of the ICS9148-13 datasheet.

The ICS9148-13 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel Pentium and PentiumPro.

An output enable is provided for testability.

Spread Spectrum is available to modulate the CPU and BUS PLL (leaving the REF, 24, 48 MHz operating normally).

.
Generates twelve processor, six bus, two 14.31818MHz, 24MHz and one 48MHz clock for USB support. Synchronous clocks skew matched to 250 ps window on CPUs and 500 ps window on BUSs CPU to BUS skew, 3.0 to 5.0ns (CPU Early) 3.0V - 3.7V supply range 48-pin SSOP package Pin Configuration Block Diagram 48-Pin SSOP Output Enable OE REF 24 48 CPU (MHz) (MHz) BUS VCO OSC Functionality FS2 0 0 0 0 1 1 1 1 FS1 0 0 1 1 0 0 1 1 FS0 0 1 0 1 0 1 0 1 CPU (1:12) in MHz 75 100 75 83.3 50 6.
