The 'ageing' of a quartz crystal results in a small change of frequency over time and this effect may have to be taken into account by the customer when designing their circuit depending upon the overall specification that needs to be achieved. There are two main causes of ageing in quartz crystals, one due to mass-transfer and the other due to stress.

Mass-Transfer

Any unwanted contamination inside the device package can transfer material to or from the SMD CRYSTALcausing a change in the mass of the quartz blank which will alter the frequency of the device. For example, the conductive epoxy used to mount the quartz blank can produce 'out-gassing' which can create oxidising material within the otherwise inert atmosphere inside the sealed crystal package and so this production process must be well controlled. Ideally the manufacturing method is as clean as possible to negate any effects and give good ageing results.

Stress

This can occur within various components of the crystal from the processing of the quartz blank, the curing of the epoxy mounting adhesive, the crystal mounting structure and the type of metal electrode material used in the device.Heating and cooling also causes stress due to different expansion coefficients. Stress in the system usually changes over time as the system relaxes and this can cause a change in frequency.

Ageing in practice

When looking at example ageing test results of crystals,it can be seen that the change in frequency is generally greatest in the 1st year and decays away with time. It must be noted however that for example if a device is specified at ±5ppm max per year; it does not follow that the ageing after 5 yrs will be ±5ppm x 5yrs, i.e. ±25ppm. In practice,the example ±5ppm ageing device may be only ±1ppm to ±2ppm in the 1st year of operation and then reduces over subsequent years. It is common to use a general 'guide-rule' for crystal ageing of ±10ppm max over 10 years although in reality it is usually much less than this. It is impossible to predict the exact ageing of a device as even parts made at the same time and from the same batch of quartz will exhibit slightly different ageing characteristics.The production process must be consistent from part to part, from the manufacture of the quartz blank, the electrode size and its placement, to the epoxy used to mount the quartz and its curing thermal profile, all have a slight affect on frequency. Devices can age negatively or positively depending upon the internal causes although parts from one batch tend to follow similar results. Generally the ageing effect is negative in over 90% of parts manufactured.

Accelerated ageing

It is common industry practice to use an accelerated ageing process to predict long term frequency movement by soaking devices at elevated temperatures and measuring frequency movement at relevant intervals. It is normal to test crystals using a passive test (i.e. non-powered). The general rule used is that soaking a crystal at +85℃ for 30 days is equivalent to 1 year of ageing at normal room temperature. If this test is extended for enough time then the recorded data can be plotted graphically to enable via extrapolation, the prediction of future long term ageing.

Frequency adjustment

Note that the ageing of quartz effectively changes the frequency tolerance of the crystal and does not directly influence the stability of the quartz over temperature to any great degree as this parameter is dictated by the 'cut-angle' of the quartz used. If using quartz oscillators that have a voltage-control function such as VCXOs, TCXOs or OCXOs, the output frequency can be adjusted back to its nominally specified value.

Design

The engineer designing a circuit using either a crystal or oscillator will generally know what overall stability figure their equipment must meet over a particular time period.

As the tolerance and/or stability of a device decreases then the more important ageing becomes. For example using a TCXO at ±1ppm stability over temperature will require ageing to be kept to relatively small values. However, if the total frequency movement allowance of a design is for example ±200ppm and a device with a rating of ±100ppm is used then a small amount of ageing can effectively be ignored.

AT Cut Crystals

For precise frequency control in radio and line communication systems, quartz crystal resonators have proved indispensable. The material properties of crystalline quartz are such that quartz resonators display stableness and Q factors that cannot be matched by other types of resonator over the frequency range from 1 MHz to 200 MHz.

Equivalent Circuit

Fig-1 shows the conventionally accepted equivalent circuit of a crystal resonator at a frequency near its main mode of vibration. The inductance LI reiperesents the vibrating mass, the series capacitance CL the compliance of the quartz element and the resistance Rl the internal frication of the element, mechanical losses in the mounting system and acoustical losses to the surrounding environment.

The shunt capacitance Co is made up of the static capacitance between the electrodes, togettier with stray capacitances of the mounting system. 

There are two zero-phase frequencies associated with this simple circuit, one is at series resonance fs, another at antiresonance fa. When used in an oscillator, crystal units will operate at any frequency within the broken lines of Fig-2 as determined by the phase of the maintaining circuit.

By changing of this reactive condition, the crystal frequency may be trimmed in a limited extent. The degree to which this frequency may be varied (frequency pulling) is inversely proportional to the capacitance ratio r(C〇 /Ci).

Load Capacitance

Many practical oscillator circuits make use of a load capacitor CL in series or parallel with the crystal, either in order to provide a means for final frequency adjustment, or perhaps for modulation or temperature compensation purposes. For the crystal load capacitance. We looking into the circuit through the two crystal terminals, the load capacitance need to specified when the crystal is paralleled mode, crystal load capacitance is calculated as below: 

Frequency Pulling

In many applications a variable capacitor (trimmer) is used as the load reactive element to adjust the frequency. The fractional frequency range available between specified values of this load reactive element is called the pulling range (PR.) and it can be calculated by using the following formula: 

Sensitivity

A useful parameter to the design engineer is the pulling sensitivity (S) at a specified value of load capacitance. It is defined as the incremental fractional frequency change for an incremental change in load capacitance. It is normally expressed in ppm/pF (10-6/pF) and can be calculated from the formula: 

It is very important to define the mean load capacitance to enable the actual crystal frequency be set within the tolerances of the specified nominal frequency. It is also important to use, wherever possible, standard values of load capacitance; for example:20pF, 30pF.

Fig-3 shows the relationship between LO.; P.R. and S. 

Frequency Pulling Calculation

An approximation to the pulling for any crystal can be calculated from this simple formula:

Resistance

The equivalent circuit of the crystal has one other important parameter: This is Ri, the motional resistance. This parameter controls the Q of the crystal unit and will define the level of oscillation in any maintaining circuit. The load resonance for a given crystal unit depends upon the load capacitance with which that unit is intended to operate. The frequency of oscillation is the same in either series or parallel connection of the load capacitance.

If the external capacitance is designated the load resonance resistance may be calculated as follows:

The equivalent shunt or parallel resistance at load resonance frequency is approximately: 

It should be remembered that Ri does not change thus the effective parameters of any user network can be readily calculated.

Frequency Temperature Characteristics

The AT-cut crystal has a frequency temperature characteristic which may be described by a cubic function of temperature. This characteristic can be precisely controlled by small variations in the exact angle at which the crystal blank is cut from the original quartz bar. Fig,4 illustrates some typical cases. This cubic behaviour is in contrast to most other crystal cuts, which have parabolic temperature characteristics.

As a consequence, the AT-cut is generally the best choice when specifying a unit to operate over a wide temperature range, and is available in a range of frequencies from 1 to 200 MHz.
