CSPEMI400G
APPLICATION INFORMATION
The CSPEMI400G provides a bidirectional filter and protector for all the signals and the power line on the SIM (subscriber
identity module) card connector. SIM cards are found in all GSM cellular phones and in some other handheld devices or card
readers. The ESD diodes protect the controller against possible ESD strikes that may occur when the connector pins are exposed
during direct contact, or during insertion of the SIM card into the card slot. The EMI filter suppresses all high ? frequency noise,
preventing the unwanted EMI signals from both entering and exiting the main board. The signals that interface with the SIM
card are the Reset, the Clock and the bidirectional data I/O, as shown in Figure 5.
Note: One channel of the CSPEMI400G with a zener
diode is not shown on the diagram.
Figure 5. Typical Application Diagram for the SIM Card Interface
For best filter and ESD performance, both GND bumps (B1, B2) of the CSPEMI400G should be directly connected to the
Ground plane. A small capacitor of about 1 m F is required next to the V CC pin of the SIM connector in order to improve stability
of the SIM card supply rail.
