Praetorian® L-C EMI Filter with ESD Protectionfor Headsets/Speakers CM1683 Features Product Description • • The CM1683 is an L-C EMI filter array with ESD protection, which integrates two Pi-filters (C-L-C) for the headset speaker. The CM1683 has component values of 100pF-3nH-100pF. 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 ±8kV, 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 ±15kV. • • • • Two channels of EMI filtering ±8kV ESD protection (IEC 61000-4-2, contact discharge) ±15kV ESD protection (HBM) Greater than -40dB of attenuation at 1GHz 8-lead, 2.00mm x 2.00mm, 0.5mm pitch uDFN package RoHS-compliant, 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 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 CM1683 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 CM1683 addresses this by having a C-L-C based EMI filter where the inductor has less than 1Ω of resistance. ©2010 SCILLC.
