EClamp2340C

www.DataSheet4U.com EMI Filter and ESD Protection for Color LCD Interface PRELIMINARY Features ‹ Flip Chip bidirectional EMI/RFI filter with integrated ESD protection ‹ ESD protection to IEC 61000-4-2 (ESD) Level4, +/-15kV (air), +/-8kV (contact) EClamp2340C PROTECTION PRODUCTS - EMIClampTM Description The EClampTM2340C is a low pass filter array with integrated TVS diodes. It is designed to suppress unwanted EMI/RFI signals and provide electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes solidstate silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They have been optimized for protection of color LCD panels in cellular phones and other portable electronics. The device consists of ten identical circuits comprised of TVS diodes for ESD protection, and a resistor capacitor network for EMI/RFI filtering. A series resistor value of 100Ω and a capacitance value of 18pF is used to achieve 20dB minimum attenuation from 800MHz to 3GHz. Each line features two stages of TVS diode protection. The TVS diodes provide effective suppression of ESD voltages in excess of 15kV (air discharge) and 8kV (contact discharge) per IEC 61000-4-2, level 4. The device is a 25-bump, 0.5mm pitch flip chip array with a 5x5 bump grid. It measures 2.6 x 2.6 x 0.65mm. The solder bumps have a nominal diameter of 0.315mm. ‹ Filter performance: 20dB minimum attenuation ‹ ‹ ‹ ‹ ‹ 800MHz to 3GHz TVS worki...
