Product Details

The MAX4948 evaluation kit (EV kit) evaluates the MAX4948 hex single-pole/double-throw (SPDT) data switch. The EV kit utilizes the MAX4948 in a Secure Digital (SD) card application. The EV kit provides two SD card sockets and a single SD card printed-circuit board (PCB) plug. The supply voltage provided by the host interface powers the MAX4948 IC and any connected SD memory cards.

The MAX4948 EV kit is a customized PCB with an SD plug designed into the board. The PCB plug is designed to resemble an SD memory card's mechanical dimensions. The PCB plug measures 50.8mm x 24mm x 1.4mm. The mechanical specifications of an actual SD memory card can be obtained from the SD Card Association.

Applications

  • Cell Phones
  • PDAs
  • SDIO/Memory Stick
  • UART Signal Switching
  • USB Signal Switching
