Intel Xeon Processor with 533 MHz Front Side Bus
Datasheet

Table 1.
Front Side Bus-to-Core Frequency Ratio
2.4.1
Bus Clock
The front side bus frequency is set to the maximum supported by the individual processor.
BSEL[1:0] are outputs used to select the front side bus frequency. Table 2 defines the possible
combinations of the signals and the frequency associated with each combination. The frequency is
determined by the processor(s), chipset, and clock synthesizer. All front side bus agents must
operate at the same frequency. Individual processors will only operate at their specified front side
bus clock frequency, (100 MHz for present generation processors).
The Intel Xeon TM processor with a 533 MHz Front Side Bus is designed to run on a baseboard
with a 133 MHz bus clock.. On these baseboards, BSEL[0:1] are considered ‘reserved’ at the
processor socket. .

PLL Filter
VCCA and VCCIOPLL are power sources required by the processor PLL clock generator. This
requirement is identical to that of the Intel Xeon processor with 512-KB L2 cache. Since these
PLLs are analog in nature, they require quiet power supplies for minimum jitter. Jitter is
detrimental to the system: it degrades external I/O timings as well as internal core timings (i.e.
maximum frequency). To prevent this degradation, these supplies must be low pass filtered from
VCC. A typical filter topology is shown in Figure 1.
The AC low-pass requirements, with input at VCC and output measured across the capacitor (CA or
CIO in Figure 1), is as follows:
< 0.2 dB gain in pass band
< 0.5 dB attenuation in pass band < 1 Hz (see DC drop in next set of requirements)
> 34 dB attenuation from 1 MHz to 66 MHz
