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 in the part number.
For example: SM7645HW and SM7645HSW 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.
Legacy part numbers are supported.
