Oscillators

An oscillator is a system which produces an output oscillating waveform, mainly used in applications where an electrical or other signal needs to be made periodic. The LFTCXO063716BULK is a type of oscillator (strictly speaking a temperature-compensated crystal oscillator, or TCXO) used in many electronic devices. In this article, we will discuss the application fields and working principle of the LFTCXO063716BULK.

Application fields

The 34.8688 MHz LFTCXO063716BULK is a coaxial SMD package type TCXO designed with low power consumption and low jitter quartz frequency. It is well suited to a wide range of applications, such as clocks in consumer electronics, industrial devices, telecommunication system clocks, automotive applications and more. In GPS systems, the LFTCXO063716BULK is used to maintain a highly precise and accurate frequency, so it can accurately determine its location. Its low noise and low jitter characteristics make it well suited for digital audio and video applications. In medical devices, it can be used in imaging and surgeries, for example in signal processing of Magnetic Resonance Imaging (MRI) scanners.

Working Principle

The LFTCXO063716BULK uses a quartz crystal as primary signal generator. The quartz material is cut in a specific shape so the crystal creates a signal at a precise frequency when a small voltage is applied across it. The frequency is limited to a range of some dozens of kilohertz to some megahertz. In order to reduce jitter and improve temperature stability of the output frequency, the LFTCXO063716BULK is designed with temperature compensation. This involves application of a frequency offset with a temperature coefficient that is opposite to that of the quartz crystal in order to compensate for temperature variation. This way, the output frequency does not vary significantly with changes in surrounding temperature.The LFTCXO063716BULK also includes an oscillator circuit, an amplifier, and a capacitor filtering circuit which maintain a consistent impedance over a range of frequencies for improved transient response to electrical noise.The resultant frequency is determined by complex interactions between the quartz, its surroundings, internal circuitry, and the tuning of voltage application (which is performed by a highly precise Voltage Controlled Oscillator, or VCO). During operation, the LFTCXO063716BULK continuously monitors the output frequency and fine-tunes the input voltage in order to stabilize the output frequency, ensuring the highest levels of accuracy and stability.
