251308-008 Datasheet, PDF (15/91 Pages) Intel Corporation – Mobile Intel Celeron Processor on .13 Micron Process and in FCPGA Package

Electrical Specifications
The AC low-pass requirements, with input at V_CCVID and output measured across the capacitor
(C_A or C_IO in Figure 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
The filter requirements are illustrated in Figure 3. For recommendations on implementing the filter
refer to the Mobile Intel^® Pentium^® 4 Processor-M and Intel^® 845MP/845MZ Chipset Platform
Design Guide.
