Features & Applications

A multiplexer is an electronic device, which is capable of accepting more than one input signal simultaneously and chooses one (or more) of the input signals as an output signal in response to the state of one or more select input. Multiplexing enables a number of individual items of information to be transmitted along the same transmission channel.

Multiplexers are used in building digital semiconductors such as CPUs and graphics controllers. They are also used in communications.

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 Phone
  • PDA
  • Digital Camera
  • Portable GPS
  • LCD Monitor
  • Home Theater PC/TV
  • All-in-One Printer 

The FSSD06UMX is available in a 24-pin  UMLP (Ultrathin Molded Leadless Package) with an operating temperature of -40 ºC to +85 ºC.
