Connection (top view):
Pad 2 and Pad 4 are common and connected
to the metal cover. They are not connected to
the crystal.
The crystal is symmetrical, there is no Pad 1
preference. The part can be rotated 180o when
being assembled on the PCB and will still
perform correctly.
Layout and application information
Trace lengths to the crystal should be kept as short as possible.
The crystal connections are sensitive to noise.
The package should be grounded for optimum performance, pad 2 and/or pad 4 connected to ground.
Marking
Marking consists of the frequency (may be truncated due to package size) and date code
Date code consists of Month Year (see codes below)
Orientation of marking may be mixed on the tape
Traceability of part is lost once removed from reel
