New chip delivers significant space and cost savings in consumerapplication design
GENEVA , Oct. 9 /PRNewswire-FirstCall/ -- By combining EMI filtering and ESDprotection for 10 high-speed signal lines in a 1.98 x 2.08 mmflip-chip package, the EMIF10-LCD03F3 from STMicroelectronics ( STM ), the world's leading supplier of integrated passive and activedevices (IPAD(TM)), saves up to 80% of board space and 49components over an equivalent discrete network, and achieves higherattenuation in the stop band.
By achieving better than -40dB attenuation in the mobile frequencyrange 900MHz to 3GHz, the EMIF10-LCD03F3 outperforms discretefilters, delivers size and cost reductions, and enhancesreliability in equipment such as cameras, cellphones, portablemedia players, GPS receivers, home entertainment products anddigital displays. With bandwidth of 200MHz at -3dB, 30pF maximumline capacitance, and 6ns max rise and fall times, the deviceprovides transparent EMI filtering for high-speed signals.
The EMIF10-LCD03F3 withstands +15kV contact discharge at inputs andoutputs exceeding IEC61000-4-2 Level 4, the highest safety standardfor ESD protection. The device's low clamping voltage also exceedsthe performance of typical discrete networks, delivering a furtherimprovement in protection and reliability while maintaining signalintegrity.
The second-order, RLC low-pass filters are fabricated using LC(inductance/capacitance) cells in ST's technology, achieving highfilter performance within a smaller silicon area than existingalternatives. By implementing 10 individual second-order filterswith ESD protection in a 24-bump, 0.4mm-pitch flip-chip package of0.6mm profile, the EMIF10-LCD03F3 saves both footprint and heightto enable miniaturization of ESD-sensitive equipment requiring highEMI filtering.
The EMIF10-LCD03F3 is in volume production now, and available at $0.45 for orders of 10,000 pieces.
