Product Summary
The IMISM532AXBT is a Spectrum Spread Clock Modulator designed for the purpose of reducing the Electro- Magnetic Interference (EMI) found in today’s high speed digital systems. The IMISM532AXBT is well suited for a wide range of digital system applications that require a reduction of radiated energy. This unwanted radiated energy is usually found in the odd harmonics of digital system clocks. By modulating the frequency of the digital clock, measured EMI at the fundamental and harmonic frequencies is greatly reduced. The applications of the IMISM532AXBT include Desktop/Laptop Computer, Modems, Scanners, Printers, Copiers, Fax Machines, MFP’s, Disk and CD-ROM Drives, Automotive and EmbeddedSystems, Networking, LAN/WAN, Digital Cameras, Games, LCD displays.
