General Description
The ICS9148-11 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro.
An output enable pin is provided for testability.
MODE allows power management functions: CPU_STOP#, PCI_STOP# & PWR_DWN#.
Key Features
- Generates four processor, six bus, one 14.31818MHz and 12 SDRAM clocks. Synchronous clocks skew matched to 250ps window on CPU, SDRAM and 500ps window on BUS clocks. CPUCLKs to BUS clocks skew 1-4 ns (CPU early) Test clock mode eases system design Custom configurations available VDD(1:3) - 3.3V ±10% (inputs 5V tolerant w/series R ) VDDL(1:2) - 2.5V or 3.3V ±5% PC serial configuration interface Power Management Control Input pins 48-pin SSOP package Block Diagram Pin Configur.
