4.6.2.1
Table 17 describes the signal quality specifications at the
processor core for the BCLK signal. Figure 4 describes the
signal quality waveform for the BCLK at the processor core
pins.
4.7
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 Celeron processor
mobile module. The voltage range is 5 volts to 21 volts.

Table 17. BCLK Signal Quality Specifications at the Processor Core
BCLK rising/falling slew-rate
Unless otherwise noted, all specifications in this table apply to all Intel mobile modules.
BCLK must rise and fall monotonically between V IL,BCLK and V IH, BCLK.
The mobile Celeron processor PSB clock overshoot and undershoot specification for 66-megahertz 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 IH (rising) or V IL (falling) voltage limits.
For proper signal termination, refer to the Clocking Guidelines in the Mobile Pentium
PCIset Advanced Platform Recommend Design and Debug Practices.
