SSDCI3128AF 数据手册 - TOP-EMC（韬略科技）

●SSDCI3128AF is a clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary (EMI)can be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator.

●The SSDCI3128AF family of mobile active EMI management ICs are unique in their design by elimiating the use of conventional PLLs.

●3128 has an input frequency range of 1MHz to 40MHz over a wide voltage range of 1.65V to 3.6V and generates a 1x spread spectrum output.

●展频原理：通过对尖峰时钟进行调制处理，使其从一个窄带时钟变为一个具有边带谐波的频谱，将尖峰能量分散到展频区域的多个频率段，从而达到降低尖峰能量，抑制EMI的效果。

●可调制展频宽度。
