Table 21
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 V
and 2.0V and fall monotonically between V
and
V
.
2. These specifications apply only when BCLK is running. See
Table 19
for the DC specifications when BCLK is
stopped. BCLK may not be above V
or below V
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 V
voltage limits. The falling edge ringback voltage is the maximum absolute voltage
that the BCLK signal can dip back to after passing the V
IL,BCLK,MAX
voltage limits.
4. Specifications labeled N/A are not available.
