Description
The SL38000-15AH a fully integrated 4 PLL low power Clock Generator with a Spread Spectrum Clock (SSC) function used for reducing Electromagnetic Interference (EMI) and general purpose frequency synthesizing. The product is designed using SpectraLinear proprietary phase-locked loop (PLL) and SSC technology to synthesize and modulate the input clock. The modulated clock can significantly reduce the measured EMI levels, leading to the compliance with regulatory agency requirements.
