MK1707
Low EMI Clock Generator
Description
The MK1707 generates a low EMI output clock from a
clock input. The part is designed to dither the LCD
interface clock for flat panel graphics controllers. 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 MK1707 offers both centered and down spread
from a high speed clock input. Refer to the
MK1714-01/02 for a crystal input and the widest
selection of input frequencies and multipliers.
ICS offers many other clocks for computers and
computer peripherals. Consult us when you need to
remove crystals and oscillators from your board.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK1707. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
