Description
The ICS181-01 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 ICS181-01 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.
ICS offers a complete line of EMI reducing clock
generators. Consult us when you need to remove
crystals and oscillators from your board.
