FSSD07: 1-Bit / 4 Bit SD/SDIO and MMC Dual-Host Multiplexer

  • The FSSD07 is a 2:1 multiplexer that allows dual Secure Digital (SD), Secure Digital I/O (SDIO), and Multimedia Card (MMC) host controllers to share a common peripheral. The host controllers can be equal to, greater than, or less than peripheral card supply with minimal power consumption. This configuration enables dual host CMD, CLK, and D[3:0] signals to be multiplexed to a common peripheral.
    The architecture includes the necessary bi-directional data and command transfer capability for single high-voltage cards or dual-voltage supply cards. The clock path is a uni-directional buffer.
    Typical applications involve switching in portables and consumer applications: cell phones, digital cameras, home theater monitors, set-top boxes, and notebooks.
