General Description
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).
