ICS181-52 Overview
The ICS181-52 generates a low EMI output clock from a clock or crystal input. The device uses IDT’s proprietary mix of analog and digital Phase Locked Loop (PLL) technology to spread the frequency spectrum of the output, thereby reducing the frequency amplitude peaks by several dB. The ICS181-52 offers center spread selection of +/-0.625% and +/-1.875%.
