CM1484

PRELIMINARY CM1484 Dual Channel EMI Filter with ESD Protection Features • • • • • • • Two channels of EMI filtering with integrated ESD protection Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network ±15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) ±30kV ESD protection on each channel (HBM) Greater than 20dB attenuation (typical) at 1 GHz 5-lead SC70 package Lead-free version available Product Description The CM1484 is a 2 channel pi-style EMI filter array with ESD protection, housed in a 5-lead SC-70 package. The CM1484 has component values of 11pF-100Ω11pF per channel. The CM1484 has a cut-off frequency of 220MHz and can be used in applications with data rates up to 80Mbps. The parts include 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 protection diodes safely dissipate ESD strikes of ±15kV, well beyond the maximum requirement of the IEC61000-4-2 international standard. Using the MILSTD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30kV. These devices are particularly well-suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of their small package and easyto-use pin assignments. In particular, the CM1484 is ideal for EMI filtering and protecting data and control lines for the I/O data ports, LCD display and camera interface in mobile handsets. The CM1484 is housed in a small, 5-lead SC70 package and is available with lead-free finishing . Applications • • • • • • LCD and Camera data lines 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.
