Table 20 describes the signal quality specifications at the processor core for the PSB clock (BCLK)
signal. Figure 4 describes the signal quality waveforms for the PSB clock at the processor core pins
For proper signal termination, refer to the “Clocking Guidelines” section in the Mobile Pentium
III Processor/440BX AGPset Recommended Design and Debug Practices (RDDP-A) 100 MHz Rev.
2.0 (SC-2760).
NOTES:
1. On the rising edge of BCLK, there must be a minimum overshoot to 2.0V. The clock must rise monotonically
between VIL,BCLK and 2.0V and fall monotonically between VIH,BCLK and VIL,BCLK.
2. These specifications apply only when BCLK is running. See Table 18 for the DC specifications when BCLK is
stopped. BCLK may not be above VIH,BCLK,MAX or below VIL,BCLK,MIN for more than 50% of the clock cycle.
3. The rising edge ringback voltage is the minimum absolute voltage that the BCLK signal can dip back to after
passing the VIH,BCLK,MIN (rising) voltage limits. The falling edge ringback voltage is the maximum absolute
voltage that the BCLK signal can dip back to after passing the VIL,BCLK,MAX (falling) voltage limits.
4. Specifications labeled N/A are not available.
