Tellurian Technologies, Inc. has been an innovator in the Frequency Control industry for over 20 years. We have built our reputation on supplying frequency based products dock-to-stock, on time or just-in-time from our ISO9001 certified factories.
Crystals are used to provide a very stable frequency reference in oscillators or as a resonator in a very narrow bandwidth filter.
A crystal controlled oscillator or clock oscillator is an oscillator which produces a stable square-wave output used to time or “clock” digital logic.
A VCXO (voltage controlled crystal oscillator) is similar to a clock oscillator except that the frequency of a VCXO may be varied by changing a control voltage on Pin 1
TCXO & VCTCXO
TCXO (temperature compensated crystal oscillator) is a crystal controlled oscillator which has additional circuitry to compensate for the normal frequency/ temperature characteristic of a crystal. This compensation minimizes frequency variation due to temperature.
This type of oscillator achieves the highest frequency stability possible with a crystal. They are typically used to control the frequency of radio transmitters, cellular base stations, military communications equipment, and for precision frequency measurement.
This is a non-crystal based oscillator which provides much higher frequencies up to the GHz range whose output frequency can be changed by applying a voltage to its control port or tuning port.
SAW FILTERS & RESONATORS
A filter depending on the propagation of surface acoustic waves through a resonant structure mounted on a piezoelectric material. Advantages include highly predictable and stable performance and very sharp cut-off characteristics; insertion loss is higher than for conventional filters, but amplification can compensate for this.
A highly selective form of quartz crystal used in electronics systems and in intermediate-frequency amplifiers of communication receivers to improve the selectivity.
Tellurian Technologies, Inc. has been an innovator in the Frequency Control industry for over 15 years. Founded in 1994, Tellurian has become a worldwide quality supplier of quartz crystals, clock oscillators, TCXO, VCXO, and crystal filters.
In 2001, Tellurian Technologies, Inc. added its VCO product line to complement its quartz frequency devices. SAW Filters and Resonators were added in 2005 to increase the product offering towards full spread spectrum frequency control.
