Description
The FSSD06 is a two-port multiplexer that allows Secure
Digital (SD), Secure Digital I/O (SDIO), and Multimedia
Card (MMC) host controllers to be expanded out to
multiple cards or peripherals. This configuration enables
the CMD, CLK, and D[3:0] signals to be multiplexed to
dual-card peripherals. It is optimized for 1-bit / 4-bit SD /
MMC applications.
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 for the FSSD06 is a uni-directional buffer with an
integrated pull-up for high-impedance mode.
Typical applications involve switching in portables and
consumer applications: cell phones, digital cameras,
home theater monitors, portable GPS units, and printers.
