World's Smallest EMI Reduction IC for Portable Applications

PHOENIX, Ariz. – Oct. 13, 2011 – ON Semiconductor (Nasdaq: ONNN) a premier supplier of high performance silicon solutions for energy efficient electronics, has introduced a new series of active clock generator integrated circuits (ICs) that manage electromagnetic interference (EMI) and Radio Frequency Interference (RFI) at the clock source, delivering system-wide EMI reduction of all clock dependent signals.

The new P3MS650100H and P3MS650103H LVCMOS peak EMI reduction clock generators are ideal for use in space constrained applications such as portable, battery powered devices – including mobile phones and tablets where EMI/RFI can be a significant challenge and compliance with regulations is a pre-requisite. Housed in a miniature four-pin WDFN package measuring 1 mm x 1.2 mm x 0.8 mm, these versatile new devices are spread spectrum clock generators that provide the industry’s smallest standalone active solution for reducing EMI/RFI at the clock source as well as downstream clock and data signals derived from the clock source.

The P3MS650100H and P3MS650103H support input voltages ranging from 1.8 volts (V) to 3.3 V, typical deviations of 0.45 percent to 1.4 percent, and reduction of EMI/RFI in clock sources with a frequency range of 15 megahertz MHz) to 60 MHz. Operating temperature range is -20 ºC to +85 ºC.

“The need to achieve EMI regulatory compliance while controlling costs and minimizing PCB real estate is a significant challenge for mobile applications,” said Ryan Cameron, vice president of Custom Industrial and Timing Products at ON Semiconductor. “Our new EMI reduction ICs address these challenges on all fronts by providing a cost-effective solution that reduces EMI/RFI at the source and at all downstream clock and data signals derived from the source. By implementing these devices early in the design cycle, design engineers potentially avoid the need for alternate solutions and the inclusion of costly additional PCB layers or shielding to deal with EMI/RFI problems.”

More IC’s from this family targeting various frequency ranges and deviations are planned for release in Q1,2012

Packaging and Pricing

The P3MS650xxxH is offered in a four-pin WDFN package and is priced at $0.37 per unit in 10,000 unit quantities.
