2.5 VOLT LOW EMI CLOCK GENERATOR
MK1728-01
IDT / ICS 2.5 VOLT LOW EMI CLOCK GENERATOR

MK1728-01
REV A 081204
Description
The MK1728-01 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 MK1728-01 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.
Features
Operating voltage of 2.5 V
Packaged in 8-pin SOIC/TSSOP
Provides a spread spectrum (Center and down spread)
clock output
Accepts a clock or crystal input (provides same
frequency dithered output)
Input frequency range of 4 to 36 MHz
Output frequency range of 4 to 36 MHz
(1X Multiplier)
Peak reduction by 8 dB to 16 dB typical on 3rd through
19th odd harmonics
Low EMI feature can be disabled
3.3 V tolerant inputs (S0,S1, FRSEL, X1)
Advanced, low-power CMOS process
