PRELIMINARY DATASHEET
2.5 VOLT LOW EMI CLOCK GENERATOR
MK1728A-01
IDT / ICS 2.5 VOLT LOW EMI CLOCK GENERATOR

MK1728A-01
REV A 051706
Description
The MK1728A-01 generates a low EMI output clock from a
clock or crystal input. Operating at 2.5 V, the part is
designed to dither the LCD interface clock for PDAs,
printers, scanners, modems, copiers, and others. Using
ICS’ proprietary mix of analog and digital Phase-Locked
Loop (PLL) technology, the device spreads the frequency
spectrum of the output, reducing the frequency amplitude
peaks by several dB. The MK1728A-01 offers both centered
and down spread from a high-speed clock input.
ICS offers many other clocks for computers and computer
peripherals. Consult ICS when you need to remove crystals
and oscillators from your board.
