PRELIMINARY CM1485 Dual Channel EMI Filter with ESD Protection Features Product Description • The CM1485 is a 2 channel pi-style EMI filter array with ESD protection, housed in a 6-lead SOT-563 package. The CM1485 has component values of 16pF-100Ω16pF per channel. The CM1485 has a cut-off frequency of 125MHz and can be used in applications with data rates up to 48Mbps. 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. • • • • • • 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 30dB attenuation (typical) at 1 GHz 6-lead SOT-563 package 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. Wireless handsets Handheld PCs/PDAs LCD and camera modules This device is particularly well-suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package and easy-to-use pin assignments. In particular, the CM1485 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 CM1485 is housed in a small, 6-lead SOT-563 package and is available with lead-free finishing.
