California Micro Devices Announces XtremeESD(R) Design Wins for New Sharp Aquos LCD TVs

Posted on: Monday, 1 June 2009, 05:30 CDT

SANTA CLARA, Calif., June 1 /PRNewswire-FirstCall/ -- California Micro Devices (Nasdaq: CAMD) announced that Sharp Electronics Corporation has selected its CM1234 low capacitance electrostatic discharge (ESD) solution to protect multiple HDMI(TM) video ports in eleven new Sharp Aquos series liquid crystal display (LCD) TVs. The CM1234 design wins include six models of the Aquos E series full HD LCD TVs and five models of the Aquos BD series LCD TVs. Designed for the US market, all the models are available now. The CM1234 delivers robust ESD protection, meeting an exacting specification of plus or minus 15kV contact discharge, and plus or minus 20kV air discharge per the IEC61000-4-2 standard, while providing superior levels of signal integrity.

"Sharp has specific requirements for higher levels of ESD protection combined with superior signal integrity performance for the HDMI ports," stated Kyle Baker, vice president of marketing for California Micro Devices. "Our PicoGuard XS(R) architecture with a unique matched impedance design that optimizes both ESD performance and signal integrity was ideally positioned to meet those exacting requirements."

Picoguard XS Impedance Matching

The PicoGuard XS architecture integrates inductors with the ESD diodes to create fixed point impedance matching for high speed data lines. Traditionally, system designers compensate for the capacitance of the ESD protection device by adding external inductance and or eliminating capacitance under the signal traces. These approaches add complexity, cost, and are PCB board dependent, limiting the ability to use multiple board vendors. The CM1234 eliminates the need for these measures, providing matched impedance with no external compensation or components required. Compared with current best in class ESD diode arrays, the CM1234 offers a 40% reduction in peak clamping voltage and a 15-40% reduction in peak residual current.
