Oscillators

Oscillators, as a kind of electronic component, are used to generate aperiodic or periodic electronic signals. Among various kinds of oscillators, ASVTX-12-C-40.000MHZ-T stands out as one of the most popular types. It is extensively applied in digital and communication devices as well as aerospace applications.

Application field

ASVTX-12-C-40.000MHZ-T oscillators are mainly used in a broad range of products that need a stable signal with low phase noise, low jitter, and excellent temperature stability, like middle and high-end mobile phones, digital cameras, tablets, servers, modems, routers, and consumer electronics. They are also used in professional broadcasting, aerospace engineering, and medical instruments.

Working principle

ASVTX-12-C-40.000MHZ-T oscillators derive a stable output signal by referring to a precise reference frequency or voltage provided by a quartz crystal. They are based on the principle of piezoelectricity. A quartz crystal consists of certain particles which can be distorted when an external electrical field is applied, or generate electricity when mechanical stress acts on them. When the electrical signals are fed into the crystal, they act as resonance frequency acceptor. Meanwhile, the oscillator circuit generates a signal with same frequency as its resonant frequency. The quartz crystal ensures the signal to have excellent stability and accuracy.

Mount type

The mount type of ASVTX-12-C-40.000MHZ-T oscillators includes surface mount (SMD) package, through hole package, and connector package. The pinout of through hole package is mainly GND-VCC-CTRL-XTAL-OUT, while the pinout of smd package is mainly VCC-GND-OUT. They are designed for different application scenarios. Surface mount packages are available for reflow or flow soldering, even for pick-and-place machines. Through hole packages feature additional pins for frequency stability and temperature stability, while connector package allows for pin-to-pin replacement and further reduced installation time.

Frequency stability

The frequency stability of ASVTX-12-C-40.000MHZ-T oscillators are as follows: ±5ppm, ±10ppm, ±20ppm, ±50ppm, ±100ppm, ±200ppm, etc. Temperature stability can be provided at ±3ppm, ±5ppm, and ±10ppm. These features enable them to support extreme operating conditions over a wide temperature range.

Conclusion

In conclusion, ASVTX-12-C-40.000MHZ-T oscillators are essential components to guarantee a reliable and stable signal in many key products. Their wide range of applications, robust design, and excellent frequency and temperature stability make them one of the most popular oscillators in the market.
