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