ICS9148-13 Datasheet | Integrated Circuit Systems

Integrated Circuit Systems, Inc. Frequency Generator & Integrated Buffers for PENTIUMTM 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). The SS_EN# pin enables the spreading when low. The SS_TYPE pin choses ±0.5% (nominally) center spread or +0, -2% (nominally) downspread modulation. High drive BUS outputs typically provide greater than 1 V/ns slew rate into 30 pF loads. CPU outputs typically provide better than 1V/ns...
