Oscillators

LFTVXO063789BULK (Low Frequency Temperature-Compensated Voltage Controlled Crystal Oscillator) is an oscillator component used in the fields of electronic engineering and radio frequency (RF) communication. It may also be used in timing and frequency devices such as clocks, quartz crystral watches and synthesizers. Oscillators are significant building blocks in the products of the RF industry.

The most important feature of LFTVXO063789BULK is its temperature-compensation capabilities. This is accomplished by using a combination of abrasion-resistant metallic coatings and precision support structure. The coated surface of the crystal particle is mean to maintain a stable oscillation frequency even in extreme temperatures.

In addition to temperature-compensation, other features of the LFTVXO063789BULK can help it meet the requirements of a range of applications. The component is stable over high temperatures, has excellent noise levels, fast start up, and wide frequency adjustment range. It also has an allowable current range of 10mA to 30mA, providing control of the oscillation frequency. The component is rated to 30MHz range.

The oscillator works on any type of crystal including AT cut, SC cut and HC-49 quartz crystals. The oscillation frequency depends on the material and shape dimensions of the crystal particle and the load capacitance, and is determined by the quartz equation:

F = 1 / {2π (sqrt (L x C))}.

Here L represents the inductive element of the crystal ohmic resistance and C is the load capacitance connected to the crystal.

To help design engineers achieve optimal use of the crystal, the LFTVXO063789BULK features an electronic feedback circuit that would sense the change resulting from its surroundings. The feedback senses the change in oscillation frequency caused by the parameter change of the crystal and modifies the oscillation frequency accordingly. The inherent temperature and aging compensations which are required for the product to function properly is provided by the associated external circuitry.

The LFTVXO063789BULK is typically used in communication systems, military and aerospace applications, medical electronics, computer systems and precision timing applications. It has wide operating temperature range (–40°C to +85°C) and the supply voltage range required is 5V. The component is also available in multiple package sizes, including 8-pin SOIC, 14TQFP and 4-pin SC-70, allowing design engineers to choose the most suitable one.

In short, LFTVXO063789BULK provides the required features and performance for many applications. Its optimized design keeps the component resistant to temperature and aging effects, while the feedback circuit provides higher precision and stability. Additionally, the component is easy to integrate into any system due to its multiple package sizes.
