Intel Pentium 4 Processor on 90 nm Process Datasheet
Electrical Specifications
2.3.1
Phase Lock Loop (PLL) Power and Filter
VCCA and VCCIOPLL are power sources required by the PLL clock generators on the processor
silicon. Since these PLLs are analog, they require low noise 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.
The AC low-pass requirements, with input at VCC are as follows:
< 0.2 dB gain in pass band
< 0.5 dB attenuation in pass band < 1 Hz
> 34 dB attenuation from 1 MHz to 66 MHz
> 28 dB attenuation from 66 MHz to core frequency
The filter requirements are illustrated in Figure 1. For recommendations on implementing the filter,
refer to the appropriate platform design guide.

NOTES:
1. Diagram not to scale.
2. No specification exists for frequencies beyond fcore (core frequency).
3. fpeak, if existent, should be less than 0.05 MHz.
