IMIFS741 datasheet

Description :

The IMIFS741 is a Frequency Spreading EMI Attenuator designed for the purpose of reducing Electro Magnetic Interference (EMI) found in today’s high speed digital systems.

The FS741 uses a proprietary technique to modulate the output clock frequency, Modout. By modulating the frequency of the digital clock, measured EMI at the fundamental and harmonic frequencies is greatly reduced.

This reduction in radiated energy can significantly reduce the cost of complying with regulatory requirements without degrading digital waveforms.
