Motional characteristics

Frequency vs. temperature fT=fO +A1*(T-TO) +A2*(T-TO)2,
There: fT – crystal’s frequency at current value of temperature T (°C),
          fO crystal’s frequency at reference value of temperature T (°C),
        TO – reference value of temperature (°C).
For getting of the greater accuracy a representation value of fT by a polynomial of the third order and definition of factor of the third order is possible as follow:
fT=fO +A1*(T-TO)+A2*(T-TO)2+A3*(T-TO)3
