Indirect compensation
A technique for temperature compensation in which a temperature sensitive circuit external to the oscillator is used to modify the crystal load reactance with temperature so that oscillator tuning is modified to reduce or eliminate the effects of temperature on the frequency of the oscillator
 

Initial frequency accuracy
A specification of the allowable range of frequencies within which the oscillator will operate at the time of shipment from the manufacturer and at a temperature of 25°C unless otherwise specified. This applies only to oscillators that are of fixed frequency (no ability to tune)
 

Input impedance
The load represented by input connections on the oscillator used for voltage control or tri-state control
 

International Atomic Time (TAI)
An atomic time scale based on data from a worldwide set of atomic clocks. It is the internationally agreed upon time reference conforming to the definition of the second, the fundamental unit of atomic time in the International System of Units (SI). It is defined as the duration of 9 192 631 770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium – 133 atom. The TAI is maintained by the Bureau International des Poids et Mesures (BIPM) in France. Although TAI was officially introduced in January 1972, it has been available since July 1955. Its epoch was set so that TAI was in approximate agreement with UT1 on 1 January 1958 (see second).
