Working Principle

The 8535AGI-21LF operates on the principle of clock buffering and spreading. It uses a synchronized digital clock buffer that is optimized for fast clock signal transmission and low EMI radiation. The stable low-power clock signal is also managed by a clock rate that is maintained by spread spectrum clock input and integrated phase-locked loop (PLL). Spread Spectrum Clocking (SSC) helps reduce EMI by decreasing the instantaneous power of the clock signal. The clock signal can be synthesized into a lower, more consistent power level over a desired frequency range. The integrated, high-speed PLL offers a wide range of clock outputs, allowing flexible clock optimization to match application requirements. The device also features autonomous skew control, which helps reduce jitter and skew by maintaining a tightly regulated clock pulse.
