Additional components

Dedicated additional capacitors are required to complete the circuit. These are listed in Table 7. Capacitor needs

below. The capacitors should be selected to maintain their capacitance value within the indicated tolerance over

the full range of maximum voltages, operating temperatures, and aging.

Capacitor values are based on capacitor positions (embedded in the camera module or external to the camera

module).

External capacitors are required to properly filter out supply noise. Optimal reference in terms of value and size is

subject to application board architecture and topology. The external capacitor values provided in the table below

may be increased to compensate real supply noise.
