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.
