CRYSTAL UNIT EQUIVALENT CIRCUIT
A quartz crystal unit in the main resonance
frequency, may be expressed as an electrical
equivalent circuit-a circuit ordinarily composed of a
series circuit consisting of an inductance, capacitance
and resistance, and a capacitance connected in
parallel to the series circuit as shown in the drawing.
Here, C0, which is commonly known as the shunt
capacitance, comprises an inter-electrode static
capacitance to which the inter-terminal stray
capacitance is added.
L1 and C1 are the equivalent constants of the quartz
crystal unit veiwed as an electrical and mechanical
oscillation system. Since both constants are
determined by such factors as the type of cut, cutting
angle, dimensions of the crystal piece, and
construction of the electrodes, and are thus
reproducible, quartz crystal units, can be
manufactured to high precisions.
R1, which denotes oscillation loss, is governed by
such conditions as the cutting, mounting, and
dimensions of the quartz crystal.

< All products >
The crystal products are designed and manufactured to
resist physical shocks.
However, in the event the crystal is subjected to excessive
impact such as being dropped onto the floor or giving
shocks during mounting. Need to make sure its

II. Soldering:
< Lead Type products >
(1) Lead wires should be soldered within 3 seconds with
the iron heated to a temperature no higher than 380°C.
(2) In solder-dip mounting, it should be within 10 seconds
with a temperature no higher than 260°C. And beware
not to heat the whole crystal unit in the dip mounting
process.
Mounting in upright bearing is recommendable (prevent
heat conduction directly to the body of a crystal unit).
(3) Heating the whole crystal unit, for example, in a reflow
oven may deterioration of the performance.
Because the holder is quite small and it is sealed by
solder material with press sealing so that such reflow
process not allowed to be proceeded.
< SMD Type products >
(1) Eutectic solder
III. Bending Lead:
< Cylinder Type products >
(1) When the lead of cylinder type crystal units need to be
bent, leave more than 1.5mm (3.0mm is recommendable)
of lead from the case in order to prevent from occurrence
of any cracks of the hermetic seal glass at the root of the
lead and use a jig for bending if possible.
(2) When bending the lead of cylinder type crystal units, do
not scrape off the solder plating from the lead surface.
IV. Mounting:
< Cylinder Type products >
(1) Soldering on the body of the cylinder type crystal unit
must be strictly avoided due to deteriorate the
characteristics or damage the products. Rubber
adhesive is recommended.

(2) When the lead needs to be bent by hand, follow the
next instructions.
① Hold the body of the Cylinder type crystal unit in
fingers.
② Pick at the part with tweezers, which you intend to
bend. There should be more than 1.5mm (3.0mm is
recommendable) from the body case.
③ Bend the lead 90° by tweezers without pulling the
lead strongly. If pulling the lead strongly may cause
any cracks of the hermetic seal glass at the root of
the lead and may cause the airtightness and the
characteristics to deteriorate.

< SMD Type products >
IX. Power supply lines:
When using an automatic loading machine, test and
confirm to cause no damage to the crystal products before
mounting.
Bending the circuit board in the process of cleaving boards
after mounting and soldering crystal products may cause
peeling off the soldering or package cracks by mechanical
stress.
Please be sure that the layout of crystal products position
is on the less stressed and the cleaving process is under
less stressed for the crystal products.
< Crystal Oscillators >
Line impedance of a power supply should be as low as
possible. To maintain stable operation, power supplies to
the Crystal Oscillator should have by-pass capacitor
(0.01µF ~ 0.1µF).
Place the capacitor as close as possible to the Crystal
Oscillator supply pins (VDD and GND).
Supply lines (VDD, GND) should be as wide as possible.
< Crystal Oscillators >
Please be sure to confirm that the pin location is proper
with electric wiring on the circuit board prior to mounting
the crystal oscillators. Mounting to the wrong pin position
will cause malfunction and damage to the crystal oscillator
and the circuit board.
V. Cleaning:
< All products >
(1) Crystal products may be affected and destroyed at
worst by ultrasonic cleaning. Please be sure to check if
your cleaning process affects any damage to crystal
products prior to use.
(2) Some kind of cleaning fluid may cause any damage to
crystal products. Please be sure to check suitability of
the cleaning fluid in advance.
X. Output line:
< Crystal Oscillators >
To reduce the line impedance of the Output line and
reduce the electromagnetic radiation, output load should
be installed as close as possible to the Crystal Oscillator.
XI. Input line:
< Crystal Oscillators >
Input pin (OE) is pulled up with an internal resister, but if it
is not used, connect it to VDD.
XII. Storage:
< All products >
Storage of Crystal products under higher temperature or
high humidity for a long term may affect frequency stability
or solderability. Please store the Crystal products under
the normal temperature and humidity without exposing to
direct sunlight and dew condensation, and avoid the
storage of Crystal products for more than 6 months, and
mount them as soon as possible after unpacking.
VI. Thermal shock:
< Crystal Oscillators >
Repetitive rapid changes with a great amplitude in
temperature may cause deteriorate the crystal unit and
break the wires inside the package. The condition must be
avoided.
VII. Static electricity:
< Crystal Oscillators >
Excessive levels of electricity may cause damage of IC
inside of a Crystal oscillator even if an anti static electricity
protection circuit is provided in the circuit board. Please be
sure to use conductive packing materials and transport
containers, and use the soldering gun and the measuring
circuit free from high-voltage leakage and provide
grounding connection while using crystal oscillators.
VIII. Noise:
< Crystal Oscillators >
Applying excessive levels of extraneous noise to power
supply or input pin may cause latch-up or spurious
phenomenon, which results in malfunction and breakdown.
Do not permit any objects, which emit a high level of noise
in a location near the Crystal Oscillator.

PRECAUTIONS IN
OSCILLATION CIRCUIT DESIGN
To utilize Crystal units characteristics fully, is necessary to
design a oscillation circuit with optimal conditions.
Based on Citizen's experience accumulated over the year,
Citizen offers such service as checking the oscillation circuit
designed by a customer with regard to items mentioning
following to ensure optimal matching between the crystal units
and the oscillation circuit.
The results of investigation with regard to items will be reported
to the customer as Citizen's "Circuit Investigation Report".

The cause of frequency changing by the power supply variation
attributes to factors on the oscillation circuit side (especially IC)
than the Crystal unit.
It is normally desirable to keep within ±5ppm in the rate of
frequency change against ±10% variation in the supply voltage.
6. Frequency tolerance over operating temperature range
Represents the rate of frequency change against various in
operating temperature.
There may be a large difference between the oscillation circuit
and the crystal unit in Frequency tolerance over operating
temperature range.

2. Load capacitance (CL)
The Load capacitance (CL) refers to an effective external series
capacitance in an assuming oscillation circuit that is viewed
from the crystal unit side.
Resonance frequency will be determined with the Load
capacitance and the crystal unit.
For this reason, differences in the load capacitance of the
oscillation circuit may cause the frequency deviations (result in
a different resonance frequency from the required one).

7. How to Check a margin for oscillation motility
① To know a margin for oscillation motility should check the
negative resistance (-R) of a oscillation circuit.
② Connect a variable resistor (VR) to the oscillation circuit in
series with the crystal unit.
③ To turn down the value resistor of VR from the NOOSCILLATION in abeyance to the oscillation START-UP.
The value shall be the negative resistance (-R) at the
oscillation starts up.
④ Adjust value of C1, C2 and Rd as the negative resistance to
be 5 times larger than the effective resistance in order to get
enough margins for oscillation motility.
And to get 10 times of -R to the effective resistance is
recommended for equipment that is required the high quality
and reliability such as auto-motive etc.

3. Negative resistance (-R)
The Negative resistance reflects the allowance and margin for
oscillation motility.
An insufficient negative resistance may cause unexpected
trouble such as No-Oscillation or slow start-up time.

4. Drive Current (i)
The drive current refers to the current flows through a crystal
unit. An excessive drive current that is applying a crystal unit
may cause the following trouble and phenomenon.
① Increase in the electromagnetic wave noise.
② Crystal element of T/F breaking off
③ Get worse the characteristics of the crystal unit such as
frequency Tolerance, Frequency Tolerance over Operating
Temperature Range, Motional resistance (Series resistance)
