摘要： For EMI reduction the current modulation profile is preferably used for frequencies over 1 GHz while the frequency deviation is increased at least to ±2.5 MHz and the modulation frequency is increased to at least 150 kHz, preferably about 260 kHz. In an alternative embodiment, the modification frequency is 1 MHz or greater so that a segmented spectrum is achieved. For clocks having basic frequency below 1 GHz, but having strong harmonics higher than 1 GHz, modulation of the foregoing is combined with the slower modulation currently used. EMI reduction is realized both at the lower and the higher harmonics.
摘要翻译：对于EMI降低，电流调制分布优选用于1GHz以上的频率，而频率偏差至少增加至±2.5MHz，并且将调制频率增加至至少150kHz，优选为约260kHz。在替代实施例中，修改频率为1MHz或更大，从而实现分段频谱。对于具有低于1GHz的基本频率但具有高于1GHz的强谐波的时钟，上述调制与当前使用的较慢调制相结合。在低次谐波和高次谐波下实现EMI降低。

摘要： A multiple output spread spectrum clock circuit is provided that reduces electromagnetic emissions when two different clocks operate at frequencies which overlap one another. Two such clock circuits are controlled so as to introduce a phase difference between the clocks as they operate through their spread spectrum profiles. The “best” phase differences are around 18%, or around 50%, between adjacent spread spectrum clock outputs. The phase difference can be controlled by starting the first clock (SSCG #1) at one point in time, while temporarily delaying the start of the second clock (SSCG #2) until the appropriate moment; alternatively, it can be controlled by starting both clocks at the same moment in time, however, SSCG #1 begins at one point in the spread spectrum profile, while SSCG #2 begins at a different point in its spread spectrum profile.

摘要： A segmented spectrum clock generator is provided that exhibits a frequency response having multiple segments that with a sharp rolloff on both sides of each individual segment's peak amplitude across the entire frequency spectrum. In order to meet proposed new CISPR-22 rules, each segment must roll off by at least 10 dB at adjacent frequencies that are ±150 kHz on both sides of (or offset from) each of the peaks. The segmented spectrum clock generator output signal is generated by a frequency synthesizer circuit that modulates the output frequency at a predetermined rate between a “lower bound” and an “upper bound” of modulation frequencies. Moreover, the modulation of the output frequencies is controlled so as to form a “segmented sperm” frequency domain output that has rather distinct peaks and valleys, and whose modulation profile has a graphical appearance of frequency vs. time that is somewhat “peaky,” although many other profile shapes could instead be used.
摘要翻译：提供了一种分段频谱时钟发生器，其展现了具有多个段的频率响应，其在整个频谱上的每个单独段的峰值振幅的两侧具有清晰的滚降。为了满足所提出的新的CISPR-22规则，每个段必须在每个峰的两侧（或偏移）的±150 kHz的相邻频率上滚降至少10 dB。分段频谱时钟发生器输出信号由频率合成器电路产生，频率合成器电路以调制频率的“下限”和“上限”之间的预定速率调制输出频率。此外，控制输出频率的调制以便形成具有相当明显的峰和谷的“分段精子”频域输出，并且其调制分布具有稍微“峰值”的频率对时间的图形外观。尽管可以使用许多其他轮廓形状。

摘要： A clock circuit includes an oscillator for generating a reference frequency signal, and a spread spectrum clock generator cooperating with the oscillator for generating a spread spectrum clock output signal having a fundamental frequency and reduced amplitude EMI spectral components at harmonics of the fundamental frequency. The spread spectrum clock generator preferably includes a clock pulse generator for generating a series of clock pulses, and a spread spectrum modulator for frequency modulating the clock pulse generator to broaden and flatten amplitudes of EMI spectral components which would otherwise be produced by the clock pulse generator. The spread spectrum modulator frequency modulates the clock pulses with specific profiles of frequency deviation versus the period of the profile. Electronic devices including the spread spectrum clock circuit and associated method are also disclosed.
