Marking and Packing Information

The part will be marked PFFM

YMDx

• Marking consists of the frequency “FF” which will be truncated to the first two digits due to package size.

• Date code consists of Year, Month and Day (see codes below)

• The x is an internal PLE production code

• Orientation of marking may be mixed on the tape

• Traceability of part is lost once removed from reel

to the metal cover. They are not connected to

the crystal.

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.
