MK2049-45
signal traces should be minimized by keeping traces
short and away from active signal traces. Use of vias
should be avoided.
3) The external crystal should be mounted just next to
the device with short traces. The X1 and X2 traces
should not be routed next to each other with minimum
spaces, instead they should be separated and away
from other traces.
4) To minimize EMI the 33
series termination resistor,
if needed, should be placed close to the clock output.
5) An optimum layout is one with all components on the
same side of the board, minimizing vias through other
signal layers (the ferrite bead and bulk decoupling
capacitor can be mounted on the back). Other signal
traces should be routed away from the MK2049-45.
This includes signal traces just underneath the device,
or on layers adjacent to the ground plane layer used by
the device.
MAN05 may also be referenced for additional
suggestions on layout of the crystal section.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK2049-45. 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.
