PRELIMINARY CM1418 Praetorian™ L-C EMI Filter with ESD Protection for Headset Speaker Applications Features • • • • • • • • 2 channels of EMI filtering ±30kV ESD protection (IEC 61000-4-2, contact discharge) ±30kV ESD protection (HBM) OptiGuard™ Coating for improved reliability at assembly Greater than 35dB of attenuation at 1GHz 6-bump, 1.720mm x 1.220mm footprint Chip Scale Package (CSP) Lead-free version available Product Description California Micro Devices’ CM1418 is an L-C EMI filter array with ESD protection, which integrates two Pifilters (C-L-C) for the headset speaker. The CM1418 has component values of 117pF-3.0nH-117pF. The parts include ESD protection diodes on all input/output pins, 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 safely dissipate ESD strikes of ±30kV, beyond the maximum requirement of the IEC61000-4-2 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 CM1418 is ideal for EMI filtering and protecting speaker output lines from ESD for the headset speaker in mobile handsets. Most speakers have impedance of 8Ω and in order to maximize the power output, the resistance of an EMI filter needs to be as low as possible and the CM1418 addresses this by having a C-L-C based EMI filter where the inductor has less than 0.35Ω of resistance. The CM1418 is available either uncoated or with OptiGuard™ coating resulting in improved reliability at assembly. The CM1418 is also available in a space saving, low profile Chip Scale Package with optional lead-free finishing. Applications • • • Headset Speaker port in mobile handsets I/O port protection for mobile handsets, notebook computers, PDAs etc. EMI filtering for data ports in cell phones, PDAs or notebook computers.
