They are not connected to the crystal. The crystal is symmetrical, there is no Pad 1 preference. The part can be rotated 180 o 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 Codes for Date Code (Month Year) Code 6 7 8 9 0 1 2 Year 2006 2007 2008 2009 2010 2011 2012 Code A B C D E F G H J K L M Month JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC |
