Intel Pentium 4 Processor on 0.13 Micron Process Datasheet
Electrical Specifications
2.4.1
Phase Lock Loop (PLL) Power and Filter
VCCA and VCCIOPLL are power sources required by the PLL clock generators on the Pentium 4
processor on 0.13 micron process. Since these PLLs are analog, 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 2-2.
The AC low-pass requirements, with input at VCC and output measured across the capacitor
(CA or CIO in Figure 2-2), is 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
Refer to the appropriate platform design guide for recommendations on implementing the filter.
