Maximum bus speed for SDIO interface is set per default to High Speed Mode (HS) with a maximum frequency of 50MHz and 3.3V signal voltage.
To achieve higher bus speed mode (SDR50 and SDR104) it is highly recommend to keep SD signal trace length less then 100mm. A load switch with quick output discharge
should be used for SD-Card power.
Please contact Avnet Integrated /MSC Technical Support if this feature is required.
