Introduction

The QE101 is a versatile 1x Active EMI management IC designed to provide system wide reduction of Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) from clock and data sources. This allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations. The QE101 family of mobile active EMI management ICs is unique in its design and is based on the phase controlled active EMI management technology. This allows operation on aperiodic as well as periodic signals. By the precise placement of the edges of the reconstructed input signal, the peak energy of the output is distributed over a wider and controlled energy band thereby significantly lowering system EMI compared to the typical narrow band signal produced by oscillators and most frequency generators. The QE101 has an input frequency range of 20MHz to 38MHz over a wide voltage range of 1.6V to 3.6V. The device has only 4 pins providing the smallest footprint ideally suited for mobile and space constrained applications. The device is available in 4-pin μDFN package.
