Integrated (U)SIM card passive filter array with ESD protection
7.3 USIM and SIM interface application schematic
The application schematic diagram depicted in
Figure 9
demonstrates how the three
NXP SIM card EMI filter and ESD protection devices are used in a typical USIM interface
application.
For example, in case a standard SIM interface without USB 1.1 is used, the two single
diodes (pins 4 and 5) can protect the VSIM line.
It is only one example dependent on layout constraints. For example, channels 1 to 8 can
be swapped with channels 3 to 6.
Also, the USB interface ESD protection pins 4 and 5 can be exchanged. Due to both sides
of the devices containing identical protection diodes, baseband and SIM card side can be
swapped, too (pin 1 with pin 8, pin 2 with pin 7 etc.).
A standard SIM interface application is depicted in
Figure 10
. In this case, both
ESD protection diodes (pins 1 and 8) are used to protect VSIM.
