Intel CELERON 1.10 GHZ - Low to High AGTL+ Receiver Ringback Tolerance; AGTL+ Signal Groups Ringback Tolerance Guidelines for Edge Finger Measurement on the S.E

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.
