Objective data sheet
The capacitance values specified for the signal channels of the MMC interface differ from
the SDHC specification. The MMC card-side interface is specified to have an intrinsic
capacitance of 12 pF to 18 pF and the total channel is limited according to the
specification to 30 pF only. Therefore, any filter device capacitance is limited to a
maximum of up to 18 pF, including the card holder and PCB traces.

MMC interface application.
