EMIF07-LCD03F3
7-line IPAD™, EMI filter and ESD protection
Features
■High attenuation in the mobile frequency range (typically better than -40 dB from 900 MHz to 2 GHz)
■Very low clamping voltage
■Low line capacitance (30 pF max) suitable for high-speed interfaces
■Maximum rise and fall time: 6 ns (10% - 90%)
■Compliant with high speed data rate
■Lead-free Flip-Chip package in 400 µm pitch
■Very thin package: 0.6 mm thickness
Benefits
■High efficiency in EMI filtering
■High bandwidth: typically 200 MHz at -3 dB
■80% space saving versus discrete solution (BOM reduction)
■High reliability offered by monolithic integration
■High reduction of parasitic elements through integration and wafer level packaging
Complies with the following standards
■IEC 61000-4-2 level 4 on inputs and outputs:
–15 kV (air discharge)
–8 kV (contact discharge)
Flip Chip (18 bumps)
Description
The EMIF07-LCD03F3 is a 7-line highly integrated L/C filter designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interference.
The EMIF07-LCD03F3 Flip-Chip packaging means the package size is equal to the die size.
This LC filter includes ESD protection circuitry, which prevents damage to the protected device when subjected to ESD surges up ±15 kV.
Applications
Displays and cameras where EMI filtering in ESD
sensitive equipment is required:
■ Mobile phones and PDAs
■ Personal and home entertainment (portable Audio, DVD players, LCD TVs)
■ Portable navigation devices
■ Digital still cameras
■ Portable gaming systems
