Notes
1X Clock Driven to
OverDrive Processor
13-1
NOTES:
1. To be used for 50 MHz or 60 MHz IntelDX2 and 75 MHz or 100 MHz IntelDX4 OverDrive processors.
2. Not 100% tested. Guaranteed by design characterization.
3. All timing specifications assume CL e 50 pF.
4. The minimum Intel OverDrive processor output valid delays are hold times provided to external circuitry.
5. A reset pulse width of 15 CLK cycles is required for warm resets. Power-up resets require RESET to be asserted for at
least 1 ms after VCC and CLK are stable.
6. TSINK temperatures are:
IntelDX2 OverDrive processor: 0§ C to a 95§ C
IntelDX4 OverDrive processor: 0§ C to a 95§ C
