Modified clock crystal oscillator, TCXO temperature compensated crystal oscillator and OCXO constant temperature crystal oscillator, upgraded crystal oscillator has been on sale at the same time!

This modified crystal oscillator board is provided to DIY players with a certain electronic circuit foundation and hands-on ability. The most basic component data, component pins, capacitance and resistance are all unclear. There is no digital multimeter electric rail, welding peripheral tools, please do it yourself solve. DIY has a certain risk. Please cut off the power and eliminate static electricity before welding. Please bear the responsibility for any problems in the modification. This shop only provides technical support, no risk!

The board modification is very easy, as long as you have the ability to remove the crystal oscillator and capacitors on the board, you can change it. If you don't understand, you can contact the online customer service, we will give you a very careful modification instruction tutorial!

The temperature difference between winter and summer in each region is much different. The crystal oscillator used by the Raspberry Pi is a low-precision crystal oscillator with high phase noise. The frequency is caused by the temperature of each region and the frequency deviation, or indoors in a place If you use it normally, go outdoors, or in other places, the frequency deviation can be solved by replacing it with this temperature-compensated crystal. It does not mean that the machine frequency does not need to be exchanged for temperature compensation. The temperature compensation is not used to correct the frequency deviation. It is to ensure that the frequency of the Raspberry Pi is always the same under various temperature environments. Of course, many devices originally have frequency deviations replaced by this. The crystal was not biased immediately after the model, it was because the crystal accuracy of the original machine was too poor and it was already biased.

Therefore, changing to a temperature-compensated crystal oscillator not only improves the level of the mid-, high- and low-frequency tri-bands, but also improves the sound field extension. The high-frequency sound background is clear and watery, the bass is steady, strong and elastic, the vocals are sweet, the charm is full, and the sound field depth is extended. The details are much more delicate.

The crystal accuracy can reach 0.1PPM, and the design installation space is consistent with the Raspberry Pi installation hole.
