彩色LCD接口ESD/EMI滤波器EClamp2454P


介绍

The EClampTM2454P is a (L-C) 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 and camera lines in cellular phones and other
portable electronics.
The device consists of four identical circuits comprised
of TVS diodes for ESD protection, and a 5-pole inductor
- capacitor network for EMI/RFI filtering. A typical
inductor value of 28nH and a capacitor value of 12pF
are used to achieve 40dB minimum attenuation at
800MHz. 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 EClamp2454P is in a 8-pin, RoHS/WEEE compliant,
SLP2116P8 package. It measures 2.1 x 1.6 x 0.58mm.
The leads are spaced at a pitch of 0.5mm and are
finished with lead-free NiPd. The small package makes it
ideal for use in portable electronics such as cell phones,
digital still cameras, and PDAs.
