56 Datasheet

Intel

Celeron

Processor up to 1.10 GHz

NOTES:

1. Unless otherwise noted, all guidelines in this table apply to all Celeron processor frequencies.

2. Guidelines are for the edge rate of 0.3 – 0.8 V/ns. See Figure 13 for the generic waveform.

3. All values specified by design characterization.

4. This guideline applies to Intel Celeron processors operating with a 66 MHz system bus only.

5. Ringback below V

REF + 250 mV is not supported.
