PSB Clock Signal Quality Specifications
and Measurement Guidelines
Table 19 describes the signal quality specifications at the
processor core for the PSB clock (BCLK) signal.
Figure 4 describes the signal quality waveform for the PSB
clock at the processor core pins.

Unless otherwise noted, all specifications in this table apply Intel mobile modules.
BCLK must rise/fall monotonically between V
IL,BCLK
and V
IH, BCLK.
This is the processor PSB clock overshoot and undershoot specification for a 66-MHz PSB operation.
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

Voltage Regulator
The DC voltage regulator (DC/DC converter) provides the
appropriate core voltage, the I/O ring voltage, and the
sideband signal pullup voltage for the Pentium II processor
with on-die cache mobile module MMC-2. The voltage range
is 5 volts to 21 volts.
