ON Semiconductor, a supplier of high performance silicon solutions for energy efficient electronics, has introduced a series of active spread spectrum clock generator integrated circuits (ICs) – for EMI reduction in portable, consumer and computing applications – namely P3P8203A LVCMOS, and P3MS650100H and P3MS650103H LVCMOS to manage electromagnetic interference (EMI) and Radio Frequency Interference (RFI).
The P3P8203A is offered in an eight-pin WDFN package and is priced at USD0.44 per unit in 10,000 unit quantities. The P3MS650100H and P3MS650103H are offered in a four-pin WDFN package and are priced at USD0.24 per unit in 10,000 unit quantities.
The P3P8203A LVCMOS peak EMI reduction clock generator targets applications such as graphics cards, computing and consumer applications. This device supports an input voltage of 3.3 V, a frequency range of 18 MHz to 36 MHz, and analog control of spread spectrum deviation by means of an external resistor.
The P3MS650100H and P3MS650103H LVCMOS peak EMI reduction clock generators are ideal for use in PCB space constrained applications such as portable, battery powered devices Ã¢â‚¬” including mobile phones and tablets where EMI/RFI can be a significant challenge and compliance with regulations is a pre-requisite. The P3MS650100H and P3MS650103H support input voltages ranging from 1.8 volts (V) to 3.3 V, typical spread spectrum 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 -20Ã‚ÂºC to +85Ã‚ÂºC.
