General Description CAMD's CSPEMI607 is an EMI filter array with ESD protection, which integrates four Pi- filters (C-RC) and 4 channels of ESD protection. The CSPEMI607 has component values of 15pF-100-15pF ). The parts include avalanche-type ESD 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 and the standalone ESD diode channels 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 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 format and easy-to-use pin assignments. In particular, the CSPEMI607 is ideal for EMI filtering and protecting data lines from ESD for the LCD display in mobile handsets. The CSPEMI607 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. 11/18/03 Tel: (408) 263-3214 * Fax: (408) 263-7846 * Website: www.calmicro.com 2 California Micro Devices 430 N.McCarthy Blvd Milpitas, CA 95035 PRELIMINARY Typical EMI filter performance (2.5V d.c., 50 environment) Cut-off Frequency (MHz) R1 () C1 (pF) 20dB Attenuation (MHz) 533 Over 25dB Range (MHz) 738 - 3000 118 100 15 All parameters in the table are typical values.
