General Description

The ICS181-51 generates a low EMI output clock from a clock or crystal input.

The device uses ICS’ 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 ICS181-51 offers center spread selection of +/-0.625% and +/-1.875%.
