LV Intel
Pentium
III Processor 512K

System Bus Clock and Processor Clocking
The BCLK and BCLK# clock inputs directly control the operating speed of the system bus
interface. All system bus timing parameters are specified with respect to the crossing point of the
rising edge of the BCLK input and the falling edge of the BCLK# input. The LV Intel Pentium
processor 512K core frequency is a multiple of the BCLK frequency. The processor core frequency
is configured during manufacturing. The configured bus ratio is visible to software in the power-on
configuration register.
Multiplying the bus clock frequency is necessary to increase performance while allowing for easier
distribution of signals within the system. Clock multiplication within the processor is provided by
the internal Phase Lock Loop (PLL), which requires constant frequency BCLK, BCLK# inputs.
During Reset, the PLL requires some amount of time to acquire the phase of BCLK and BCLK#.
This time is called the PLL lock latency, which is specified in
timing parameter for T18.

Maximum Ratings

Table 6
contains the LV Intel Pentium
absolute maximum and minimum is neither implied nor guaranteed. The processor should not
receive a clock while subjected to these conditions. Functional operating conditions are provided in
the AC and DC tables. Extended exposure to the maximum ratings may affect device reliability.
Furthermore, although the processor contains protective circuitry to resist damage from static
electric discharge, one should always take precautions to avoid high static voltages or electric
fields.
