General Description CAMD's CM1423 CM1423 is an EMI filter array with ESD protection, which integrates six (6) Pi- filters (C-R-C) and 4 channels of ESD protection. The CM1423 CM1423 has component values of 12pF-100-12pF. 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). The ESD diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±15kV, beyond the maximum requirement of the IEC 61000-4-2 international standard. Using the MILSTD-883 MILSTD-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 format and easy-to-use pin assignments. In particular, the CM1423 CM1423 is ideal for EMI filtering and protecting data lines from ESD for the Secure Digital (SD) Card interface slot in mobile handsets. The CM1423 CM1423 is an all-inclusive solution for the SD card interface since its EMI filters provide the proper cut-off frequency to attenuate unwanted signals while limiting current with the appropriate pull-up resistor values. The CM1423 CM1423 is available in a space-saving, low-profile, chip-scale package, and is fabricated with one of California Micro Devices' semiconductor processes.

Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin (i.e. if ESD is applied to pin A1 then clamping voltage is measured at pin C1). Unused pins are left open. These parameters are guaranteed by design. 11/11/03 Tel: (408) 263-3214 · Fax: (408) 263-7846 · Website: www.calmicro.com 3 PRELIMINARY California Micro Devices 430 N.
