Description
The ICS180-52 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 ICS180-52 offers center spread selection of
+/-0.625%
and +/-1.875%. 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.
