Product Description

Functional Description
The CM1457 is an inductor-based (L-C) EMI filter array with ESD protection, which integrates four, six, or eight filters in a CSP form factor with 0.40mm pitch. Each EMI filter channel of the CM1457 is implemented with the component value of 6pF-35nH–4.7pF-35nH–1.8pF. The cut-off frequency at -3dB attenuation is 300MHz and can be used in applications where the data rates are as high as 160Mbps, while providing greater than -35dB attenuation over the 800MHz to 2.7GHz frequency range.
Features
• Four, six, or eight channels of EMI filtering
• ±15kV ESD protection (IEC 61000-4-2, contact discharge) at external pins
• Greater than -40dB of attenuation at 1GHz MIL_STD_883 international ESD standard
• Chip Scale Package (CSP) with 0.40mm pitch and 0.25mm CSP solder ball which features extremely low parasitic inductance for optimum filter and ESD performance
• OptiGuardTM coating for improved reliability at assembly
• RoHS-compliant, 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 computer
• Wireless handsets
• Handheld PCs/PDAs
• LCD and camera modules
