ESD/EMI Protection for Color LCD Interfaces
PROTECTION PRODUCTS
- EMIClamp TM Description
The EClamp TM2342N 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.
PRELIMINARY
Features
Bidirectional EMI/RFI filter with integrated TVS for ESD protection ESD protection to IEC 61000-4-2 (ESD) Level4,
+/-15k V (air), +/-8k V (contact)
Filter performance: 30d B minimum attenuation
1GHz to 2.5GHz TVS working voltage: 5V Resistor: 100Ω +/- 15% Input Capacitance: 20p F (VR = 0V) Protection and filtering for eight lines Solid-state technology
The device consists of eight identical circuits prised 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 20p F are used to achieve 30d B minimum attenuation from 1GHz to 2.5GHz. Each line Features two stages of TVS diode protection. The TVS diodes provide effective suppression of ESD voltages in excess of 15k V (air discharge) and 8k V (contact discharge) per IEC 610004-2, level 4. The EClamp2342N is in a 16-pin, 0.5mm pitch QFN package. It measures 3.0 x 3.0 x 1.0mm. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDA’s.
