November 12, 2012 – ON Semiconductor (Nasdaq: ONNN), the premier supplier of high-performance silicon solutions for energy-efficient electronic products, introduces a new series of active spread-spectrum clock generator integration The circuit (IC) P3P8203A manages the electromagnetic interference (EMI) and radio frequency interference (RFI) of the clock source, and reduces EMI in the system range for all clock-dependent signals.
 
The target applications for the P3P8203A LVCMOS peak EMI reduction clock generator are graphics card, computing, and consumer applications. This device supports 3.3 volts (V) input voltage from 18 MHz to 36 MHz and controls spread-spectrum deviation with external resistor simulation. System designers choose different values ​​of this external resistor to provide the desired amount of spread spectrum deviation at the output, so they can customize the application more flexibly, and achieve the requirements to reduce EMI in their applications. The P3P8203A is available in an 8-pin, 2 mm x 2 mm x 0.8 mm WDFN package, making it ideal for applications where printed circuit board (PCB) space is limited. Operating temperature range is 0 ° C to + 70 ° C.
 
The P3MS650100H and P3MS650103H LVCMOS peak EMI reduction clock generators are well-suited for applications where PCB space is limited, such as portable battery-powered devices such as mobile phones and tablets; in these applications, EMI / RFI can be a significant challenge and compliance with EMI / RFIF Specification is a prerequisite. These two new universal spread-spectrum clock generators use only 1 mm x
The 1.2 mm x 0.8 mm miniature 4-pin WDFN package provides the industry's smallest stand-alone active solution for reducing EMI / RFI of clock sources and downstream clocks and data signals derived from clock sources. The P3MS650100H and P3MS650103H support an input voltage range of 1.8 V to 3.3 V, with a typical spread-spectrum deviation of 0.45% to 1.4%, reducing the EMI / RFI of clock sources in the 15 MHz to 60 MHz frequency range. Operating temperature range is -20ºC to + 85ºC.
 
Ryan Cameron, vice president of industrial and timing products at ON Semiconductor, said: "Complying with EMI specifications while controlling costs and minimizing PCB footprint are major challenges for portable and computing applications. Our new EMI reduction IC addresses these challenges and provides cost-effective Solution to reduce the EMI / RFI of the clock source and the downstream clock and data signals derived from the clock source. Design engineers can use these devices early in the design cycle without the need for other solutions or the addition of costly extra PCB layers or shields. Dealing with EMI / RFI issues. "
 
 
Package and price
The P3P8203A is available in an 8-pin WDFN package and is priced at $ 0.44 each in 10,000-unit quantities. The P3MS650100H and P3MS650103H are available in 4-pin WDFN packages. The unit price is $ 0.24 per 10,000 units.
