ON Semiconductor, supplier of high performance silicon solutions for energy efficient electronics recently introduced a series of active clock generator integrated circuits (ICs) called P3MS650100H and P3MS650103H LVCMOS. These clock generator ICs manage electromagnetic interference (EMI) and Radio Frequency Interference (RFI) at the clock source. They deliver a system-wide EMI reduction of all clock dependent signals.

The P3MS650100H and P3MS650103H LVCMOS peak EMI reduction clock generators are ideal for use in space constrained applications. This includes portable, battery powered devices such as mobile phones and tablets in which EMI/RFI can be a significant challenge and compliance with regulations is a pre-requisite.

These 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 need to achieve EMI regulatory compliance while controlling costs and minimizing PCB real estate is a significant challenge for mobile applications,” says 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,” adds Cameron.

More ICs from this family targeting various frequency ranges and deviations are planned for release in the 1st quarter of 2012.

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

ON Semiconductor has a broad portfolio of power and signal management, logic, discrete and custom devices that helps customers solve their design challenges in automotive, communications, computing, consumer, industrial, LED lighting, medical, military/aerospace and power applications. It has a value-added supply chain and a network of manufacturing facilities, sales offices and design centers in key markets throughout North America, Europe, and the Asia Pacific regions.
