R-C Protection Devices Target 3G Handset LCD Interfaces
Operating in frequencies from 1.8 GHz to 2.5 GHz, Semtech’s EClamp237xK family resistor-capacitor (R-C) protection devices serve high-resolution color LCD interfaces in GSM- and CDMA-based 3G handsets. The RoHS- and WEEE-compliant units exhibit a C(in) value of 20 pF, series resistance of 100 O, and min. attenuation of >30 dB. The products offer TVS diodes for ESD protection to IEC 6100-4-2 Level 4 (±15-kV air, ±8-kV contact) and an R-C network for EMI and RFI filtering for 4, 6, or 8 lines. The SLP-packaged components present a 500-micron package height and a 400-micron lead pitch. Pricing ranges from $0.25 to $0.40 each in 1,000 quantities.
