Marking Legend:
PLE = Pletronics
FF.FFF M = Frequency in MHz
YYWW or YWW or YMD = Date of Manufacture (year and week, or year-month-day)
All other marking is internal factory codes
Specifications such as frequency stability, supply voltage and operating temperature range, etc.
are not identified from the marking. External packaging labels and packing list will correctly
identify the ordered Pletronics part number.

Legacy Part Numbers:
‘S’ Denoted Symmetry of 45%/55% at 50% of V_CC. This is now the standard Duty Cycle and is no longer needed
inthe part number. We will still support part numbers with the ‘S’. For example: SM5545TX and SM5545TSX
describe the same specifications and can be used interchangeably by the customer.
-30 or -50 Denoted Output Load other than the standard 15 pF. Data sheets now reflect the specifications at all
available loads so this load designation is no longer needed. We will still support part numbers with this load
designation.
