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 con-
nected 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 mechani-
cal 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.
