System Bus Clock (BCLK) Signal Quality Specifications and
Measurement Guidelines
Table 21
describes the signal quality specifications at the processor core for the Pentium II
processor system bus clock (BCLK) signal.
Table 22
describes guidelines for signal quality
measurement at the processor edge fingers.
Figure 13
describes the signal quality waveform for the
system bus clock at the processor core pins.
Figure 14
describes the signal quality waveform for the
system bus clock at the processor edge fingers.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Pentium
II processor frequencies and cache sizes.
2. This is the Pentium II processor system bus clock overshoot and undershoot specification for 100-MHz system bus
operation.
3. The rising and falling edge ringback voltage specified is the minimum (rising) or maximum (falling) absolute voltage
the BCLK signal can dip back to after passing the V
IH
(rising) or V
IL
(falling) voltage limits. This specification is an
absolute value.
