展频晶振(Spread Spectrum)系列用于数字电子系统中,以降低电磁干扰(EMI)。展频晶振采用专有PLL锁相和展频技术来合成和调制晶体输出频率。有效降低晶振基波和谐波辐射干扰程度,使产品达到符合电磁兼容性(EMC)要求之目的。 Flexible modulation rate options 展频方式及程度可选如下: Center Spread 中心展频: ±0.25% ~ ...
- Spectrum spread range = Fref * ss_stop/DENOM- Modulation frequency = Fref * ss_step/(2*ss_stop) I created the above function based on that formula, but the signal strength does not change. Additionally, I analyzed the code and found that the semc clock is coming from kCLOCK_PllArm...

A spread spectrum modulation system uses an input signal and a spreading signal for modulating the input signal. The spreading signal includes a plurality of component signals spaced apart substantially equally in frequency and with substantially equal amplitudes. Each component signal is phase encoded ...
