Description
The ICS180-01 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 ICS180-01 offers down spread selection of -1.25%
and -3.75%. Refer to the MK1714-01/02 for the widest
selection of input frequencies and multipliers.
IDT offers a complete line of EMI reducing clock
generators. Consult us when you need to remove
crystals and oscillators from your board.
