Programmable Oscillators

Programmable oscillators are oscillators used in various applications to provide various frequencies. They are used to control the frequency and timing of electronics, radio-frequency (RF), and other signal sources. They are used in many systems and devices, ranging in size from small microcontrollers to large electronic systems. Programmable oscillators can come in a variety of forms such as voltage-controlled (VCXO), temperature-compensated (TCXO), and quartz crystal oscillators (XO).

There are many advantages to using programmable oscillators. For one, they have the ability to provide an adjustable range of frequencies, allowing for multiple frequency-dependent applications. They can also provide higher frequency accuracy and stability than analog oscillators due to their digital nature. In addition, they are often easier to use as they are programmed from a software interface.

In order to meet the needs of various applications, programmable oscillators come in a variety of frequency options. Choose the frequency step size, the center frequency, and the maximum signal level according to the desired use case. Examples of typical frequency steps are 100 kHz, 500 kHz, and 5 MHz.

The 500SEBE-ACH is an example of a programmable oscillator. It is a temperature-compensated, voltage controlled crystal oscillator (TCVCXO) and utilizes a quartz crystal acting as an inductor. This oscillator has a high frequency accuracy of 0.3 ppb, making it ideal for high-precision applications. It operates over a wide frequency range of 16960MHz to 17660MHz, and boasts fast settling time of 2 ms.

The 500SEBE-ACH can be programmed from the GUI software to change the center frequency and the large/low frequency steps. It has a nominal frequency stability of ± 0.5 ppm from -30℃ to +85℃. In terms of power, it consumes up to 1.7 W with a default voltage of 3.3 V. This oscillator also comes with EMI filters to provide effective EMI suppression.

Overall, the 500SEBE-ACH is a great choice for applications that require high frequency accuracy and stability. It is easy to use and provides a wide range of frequency options, allowing for multiple application scenarios. With its fast settling time of 2 ms, this oscillator is perfect for high-precision applications where time and accuracy are of essence.
