The primary high-performance silicon solution for high energy electronics suppliers Ansen American Semiconductors (On Semiconductor, Nasdaq, USA) launched a new series of active spread spectrum clock generator integrated circuit (IC) P3P8203A, management Electromagnetic Interference (EMI) and RF Interference (RFI) of Clock Source Reduces EMIs in the system range for all signals that depend on the clock.
P3P8203A LVCMOS peak EMI reduces the target application of clock generators for graphics cards, calculations and consumption. This device supports 3.3 volts (V) input voltages, and the frequency range is 18 MHz to 36 MHz, and the spread spectrum deviation is controlled by external resistance. System Designers Choose Different values of the external resistance to provide spreading deviations from the output to provide the wi-spectrum deviation, which can be more flexibly customized to achieve the requirements of reducing EMI in their applications. The P3P8203A uses 8-pin, 2 mm x 2mm x 0.8 mm WDFN package, which is ideal for applications where the printed circuit board (PCB) space is limited. The operating temperature ranges from 0 ° C to + 70 ° C.
P3MS650100H and P3MS650103H LVCMOS peak EMI reduced clock generators ideal for PCB space restricted applications, such as mobile phones and tablets such as portable battery powered equipment; EMI / RFI may be major challenges, and follow EMI / RFIF The specification is a prerequisite. These two universal new spreading clock generators have a miniature 4-pin WDFN package for only 1 mm x1.2 mm x 0.8 mm, providing the industry's smallest and active program for reducing clock source and originating from Downstream clock and data signal of the clock source EMI / RFI. P3MS650100H and P3MS650103H support 1.8 V to 3.3 V input voltage range, typical spread spectrum deviation is 0.45% to 1.4%, and the EMI / RFI of the clock source of 15 MHz to 60 MHz frequency range is reduced. The operating temperature range is -20oC to + 85oC.
RYAN CAMERON, Vice President of Semiconductor Industry and Timples, said: "Compliance with EMI specification simultaneously controls costs and minimizes PCB footprints, is a major challenge for portability and computing applications. Our new EMI reduces IC to solve these challenges, provide high performance ratio The scheme, reduce clock source and EMI / RFI from the downstream clock and data signals derived from the clock source. Design engineers use these devices in design cycles, there is no need to adopt other programs, and there is no need to add high-cost additional PCB layers or mask. Handling EMI / RFI issues. "
