CM1423 Secure Digital (SD) Card EMI Filter Array with ESD Protection


Provides EMI filtering and ESD protection for an SD port on a mobile device Six channels of EMI filtering with ESD protection Four channels of ESD protection ±15kV ESD protection on all I/O pins (IEC 610004-2, contact discharge) ±30kV ESD protection (HBM) Better than 25dB of attenuation at 1GHz for 12pF100 -12pF filter configuration Integrates 34 components into small form factor CSP solution x 1.458mm footprint Chip Scale Package Chip Scale Package features extremely low lead inductance for optimum filter and ESD performance Available with OptiGuardTM coating for improved reliability at assembly Lead-free version available

California Micro Devices's is an EMI filter array with ESD protection, which integrates six Pi- filters (C-R-C) and four channels of ESD protection. The CM1423's filters have component values of 12pF100-12pF. The part includes ESD protection diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). All the ESD diodes safely dissipate ESD strikes of ±15kV, beyond the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30kV. This device is particularly well-suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package and easy-to-use pin assignments. In particular, the CM1423 is ideal for EMI filtering and protecting data lines from ESD for the Secure Digital (SD) Card interface slot in mobile handsets. The is an all-inclusive solution for the SD card interface since its EMI filters provide the proper cut-off frequency to attenuate unwanted signals. The CM1423 is manufactured in a space-saving, lowprofile, chip-scale package, and is optionally available with OptiGuardTM coating for improved reliability. It is also available with lead-free finishing.


Secure Digital (SD) Card data lines in mobile handsets SD Card interface protection for other mobile electronics such as MP3 players, PDAs and digital cameras I/O port protection for mobile handsets, notebook computers, PDAs etc. EMI filtering for data ports in cell phones, PDAs or notebook computers.

In a typical SD Card application, (A6) is connected C4 (C6). See example given in applications section.
