NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Celeron processor frequencies.
2. This is the Intel Celeron processor system bus clock overshoot and undershoot measurement guideline.
3. The rising and falling edge ringback voltage guideline is the minimum (rising) or maximum (falling) absolute
2. This is the Intel Celeron processor system bus clock overshoot and undershoot measurement guideline.
3. The rising and falling edge ringback voltage guideline is the minimum (rising) or maximum (falling) absolute
voltage the BCLK signal may dip back to after passing the V
IH
(rising) or V
IL
(falling) voltage limits. This
guideline is an absolute value.
4. The BCLK at the processor edge fingers may have a dip or ledge midway on the rising or falling edge. The
midpoint voltage level of this ledge should be within the range of the guideline.
5. The ledge (V7) is allowed to have peak-to-peak oscillation as given in the guideline.
