Low EMI Clock Generator
Description
The MK1704A is an upgraded version of the MK1704
and is recommended for all new designs. It offers more
reduction in the frequency amplitude peaks and will
support frequencies up to 140 MHz.
The MK1704A generates a low EMI output clock from a
clock input. The part is designed to dither the LCD
interface clock or other clocks for flat panel graphics
controllers. The MK1704A uses ICS’ proprietary
mixture of analog and digital Phase Locked Loop (PLL)
technology to synthesize the frequency. It also uses
ICS’ patented technique to spread the frequency
spectrum of the output, thereby reducing the frequency
amplitude peaks by several dB.
ICS offers many other clocks for computers and
computer peripherals. Consult ICS when you need to
remove crystals and oscillators from your board.
Features
8 pin SOIC package
Available in Pb (lead) free package
Provides a spread spectrum output clock
Supports leading flat panel controllers
Accepts a clock input, provides same frequency
dithered output
Optimized for higher resolutions that require up to
140 MHz, as well as 40 MHz (SVGA) and 65 MHz
(XVGA) clocks
Peak reduction by 7 dB - 14 dB typical on 3rd - 19th
odd harmonics
Low EMI feature can be disabled
Operating voltage of 3.3V or 5V
Advanced, low power CMOS process
See the MK1714-01 for a multiplier with low EMI
which can operate from a crystal
