Table 24 details the bulk capacitance requirements for the system electronics.
Table 24. Bulk Capacitance Requirements
NOTES:
1. Placement of above capacitance requirements should be located near the connector.
2. V_CLK filtering should be located next to the system clock synthesizer.
3. The Ripple current specification depends on the V_DC input for the mobile module. See Figure 7 below.
4. If Tantalum* Capacitors are used, a 50% voltage derating practice must be observed. For example, a 5.0-V
rail requires a 10.0-V rated capacitor.
5. In order to reduce ESR, Intel recommends the use of multiple bulk capacitors rather than a single large
capacitor.
6. Intel strongly recommends that system manufacturers pay close attention to capacitor design considerations.
Specifically, the "Capacitance vs. Temperature De-rating Curve," "Capacitance vs. Applied DC Voltage De-
rating Curve," and the "Capacitance vs. Frequency De-rating Curve." Some capacitor dielectrics are
particularly susceptible to these conditions, for example Y5V ceramic capacitors.
7. Specifications labeled N/A are not available.
