MAX4948 Evaluation Kit
SD Sockets
The two on-board SD card sockets accommodate both
a standard SD memory card and a thin SD memory
card. The pinout for each SD socket is listed in Table 3.
Table 3. P1 and P2 Pinout
Header J2
The 16-pin, dual-row header (J2) connects the
COM1–COM6 terminals to the PCB plug (P3). In addi-
tion, the VDD supply voltage from the SD card reader/SD
card port is routed through J2 to each VCC pin of socket
P1 and P2. See Table 5 for a pin-to-pin association

Header J1
The 24-pin, dual-row header (J1) connects the P1 and
P2 SD sockets to the normally open (NO) and normally
closed (NC) terminals. The P1 socket is connected
through header J1 to the switches ’ NO terminals
(NO1–NO6). The P2 socket is connected through head-
er J1 to the switches’ NC terminals (NC1–NC6). See
Table 4 for a pinout of header J1.

*VCC: SD memory card supply voltage.
**VDD: Host-interface supply voltage.
SD PCB Plug
The MAX4948 EV kit was designed on a customized
PCB to allow for actual application evaluation. The SD
plug (P3) is an extension of the PCB and can be insert-
ed into a standard SD card socket. This design allows
two SD memory cards to be switched into a single SD
card socket. See Table 6 for the SD plug’s net associa-
