Advantages and disadvantages of programmable crystal oscillators

Programmable crystal oscillators have gradually entered people's eyes in recent years. What is a programmable crystal oscillator and what is the difference between it and a regular crystal oscillator? What are the advantages and disadvantages of programmable crystal oscillators?

1. What is a programmable crystal oscillator

Programmable crystal oscillator is a crystal oscillator device that can be programmed to set its output frequency. Its characteristics lie in its high flexibility and adjustability, enabling precise matching of required clock signals in various electronic product design processes. Programmable crystal oscillator is a type of crystal oscillator that can adjust its frequency through an external programmer. It adopts advanced digital signal processing technology and has the characteristics of adjustable frequency, adjustable phase, and good stability. Compared with traditional active crystal oscillators, programmable crystal oscillators are more powerful and flexible in frequency adjustment range and accuracy.

Programmable crystal oscillators have a wide range of applications, including communication devices, electronic clocks and timers, medical instruments, and industrial automation control systems. In communication devices, programmable crystal oscillators can adjust the oscillation frequency according to different frequency requirements to meet the needs of different signal processing. In electronic clocks and timers, it can accurately time and ensure the accuracy of time. On medical devices, it can adjust the frequency as needed to meet different treatment requirements. In industrial automation control systems, it can ensure the continuity and stability of production.

⑥ Supports multiple working voltage matching options including 1.8V, 2.5V, 2.8V, and 3.3V!

⑦ Support various precision matching such as ± 10PPM, ± 20PPM, ± 25PPM, ± 30PPM, ± 50PPM, etc!

2. Advantages of Programmable Crystal Oscillators

Programmable crystal oscillator refers to providing crystal oscillator parameters, such as frequency deviation, operating voltage, load capacitance, and frequency, to the crystal oscillator manufacturer. The manufacturer can program these parameters through devices such as computers and press the OK button to write them onto a blank chip. Normally, the production lead time is 1-3 days. We know whether it is a conventional passive crystal oscillator or an active crystal oscillator. In the case of chip stock, the production lead time is 2-3 weeks, the conventional lead time is about 4-6 weeks, and the special period is 2-3 months. Therefore, in terms of lead time, programmable crystal oscillators not only have advantages in lead time, but also have flexible programmable properties in terms of frequency. In terms of functionality, completely eliminate the issue of temperature drift.
