SPECIFYING SURFACE MOUNT SIMPLE PACKAGED
CRYSTAL OSCILLATORS (SM SPXOs)
A typical surface mount SPXO specification reads like
this:
19.66080MHz IQXO-57 B E TR T
Frequency
Model Number
Frequency Stability
Frequency Tolerance
Packaging
Additional Text code (for non-standard product)
The following notes define each element of the specification.
Frequency
Frequency is normally specified in kilohertz (kHz) up to
999.999 kHz and in megahertz (MHz) from 1.0MHz. All
our computer-generated transaction documents follow this
standard convention automatically.
The frequency should be described to seven significant
figures. If seven significant figures are not used, we assume
that any figure that might follow those given may be taken as
zero. Thus a frequency given as 16.6MHz will be taken as
16.60, not 16.6667.
Please contact the sales office for details of developed
frequencies.
Model Number
The model number incorporates information which
describes output compatibility and holder style.
Frequency Stability
The frequency stability of a surface mount oscillator includes
the initial adjustment tolerance at room temperature, the
tolerance over operating temperature range and the effect of
supply voltage variation. This value is specified as ‘parts per
million’ (ppm) and is available in four ranges; ±15ppm,
±25ppm, ±50ppm & ±100ppm.
The following codes apply:
A = ±25ppm
B = ±50ppm
C = ±100ppm
N = ±15ppm
Non-Standard Frequency Tolerances
During manufacture, it is possible to adjust some surface
mount SPXO’s to a specific tolerance at room temperature.
The frequency tolerance forms part of the frequency
stability. These oscillators have a second letter code to
indicate the frequency tolerance.
E = ±10ppm
F= ±25ppm
Operating Temperature Range
0 to 70°C
–10 to 70°C
–40 to 85°C
–55 to 125°C
Although in general oscillators will continue to operate
outside their normal temperature range with a degradation
in frequency stability, damage can result if the temperatures
reached are excessive.
Packaging
Tape and Reel packaging is available as an option on many
of the products outlined in the SM SPXO chapter.
Unless individual datasheets state Tape and Reel packaging,
items will be bulk packed. Please note: only complete Reels
are sold.
BU = Bulk packed
TR = Tape & Reel packed
Addtional Text Code
If the product is non-standard, the letter ‘T’ will appear at
the end of the product specification. This refers to additional
text on the sales order/quotation to identify the non-standard
requirements.
Outline Drawings
Dimensions on the oscillator outline drawings are shown
only as a guide. Precise dimensions of oscillator holders are
available from our factory upon request. All dimensions are
shown in mm (& inches) and are nominal unless otherwise
stated. All outlines are at a scale of 1:1 unless otherwise
specified.
Delivery Options
The following Express delivery options are available for
certain oscillators; timescales refer to despatch from our
factories.
5 working days (Express service)
7 working days (Express service)
10 working days (Express service)
Prices for larger quantities and longer delivery times are
generally lower due to substantially reduced manufacturing
costs.
Marking
Product will be indelibly marked as detailed in the individual
data sheets.
Where space is limited some or all of the
information will be omitted/truncated at C-MAC
Frequency Products discretion. Full product description will
be found on the individual batch packaging.
