Industry's smallest active clock generator ICs reduce EMI issues in portable applications

October 14, 2011 // By Paul Buckley
ON Semiconductor has introduced a new series of active clock generator 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 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 claim to 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 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 MHz) to 60 MHz. Operating temperature range is -20  to +85 ºC.
More ICs from this family targeting various frequency ranges and deviations are planned for release in Q1,2012

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