| Part Number | ICS9147-09 |
| Manufacturer | Integrated Circuit Systems |
| Description | The ICS9147-09 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro,AMD or Cyrix processors. Four bidirectional I/O pins (FS0, FS1, FS2, BSEL) are ... |
| Features |
Total of 15 CPU speed clocks: - Two copies of CPU clock with VDDL (2.5 to 3.3V) - Twelve (12) SDRAM (3.3v) plus one CPUH/AGP (3.3V) clocks Six copies of BUS clock (synchronous with CPU clock/2 or asynchronous 32 MHz) 250ps output skew window for CPU andSDRAM clocks and 500ps window BUS clocks. CPU clocks to BUSclocks skew 1-4ns (CPU early) Two copies of Ref. clock @14.31818 MHz (One driven by VDDL as IOAPIC) One 48 MHz (3.3 V TTL) for USB support and single 24 MHz. Separate VDDL for CPUL (1:2) clock buffers and IOAPIC to allow 2.5V output (or Std. Vdd) 3.0V 3.7V supply range w/2.5V compati... |
