The CM1483 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. • • • 2 channels of EMI filtering ±8kV ESD protection (IEC 61000-4-2, contact discharge) ±15kV ESD protection (HBM) Greater than -40dB of attenuation at 1GHz TDFN-08 package 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 CM1483 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 CM1483 addresses this by having a C-L-C based EMI filter where the inductor has less than 1Ω of resistance. The CM1483 is available in a small, low-profile (2mm x 2mm) 8-lead TDFN package in a lead-free finish. ©2010 SCILLC. All rights reserved.
