MK1704A
4) An optimum layout is one with all components on the
same side of the board, minimizing vias through other
signal layers. Other signal traces should be routed
away from the MK1704A. This includes signal traces
just underneath the device, or on layers adjacent to the
ground plane layer used by the device.
Powerup Considerations
To insure proper operation of the spread spectrum
generation circuit, some precautions must be taken in
the implementation of the MK1704A.
1) An input signal should not be applied to ICLK until
VDD is stable. This requirement can easily be met by
operating the MK1704A and the ICLK source from the
same power supply.
2) LEE should not be enabled (taken high) until after
the power supplies and input clock are stable. This
requirement can be met by direct control of LEE by
system logic; for example, a “power good” signal.
Another solution is to leave LEE unconnected to
anything but a 0.01
F capacitor to ground. The pullup
resistor on LEE will charge the capacitor and provide
approximately a one millisecond delay until spread
spectrum is enabled.
3) If the input frequency is changed during operation,
disable spread spectrum until the input clock stabilizes
at the new frequency. LEE should be disabled for 10
s
minimum.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK1704A. 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.
