Description
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.
