A-Crystal mainly produces 32.768kHz Tuning Fork Crystals which includes watch crystals packaged in different materials: Metal/Ceramic /Plastic Packages. Also accepte any specification of quartz crystals, oscillators and sensors that you need. Standard Load Capacity available in 6pF,7pF,9pF,12.5pF. And the operate over extended operating temperature ranges up to -45 to 125°C. The frequency tolerance and temperature stability down to +/-5ppm, frequencies from 10kHz to 250MHz.
A-Crystal launches a new design product - Rubidium Atomic Clock. We have stable power consumption: normal temperature is less than 20W, low temperature is less than 25W; multi-channel output: 2 channels of 10MHz and 1 channel of 5MHz output, which can meet the reference input of different equipment; lock indication: easy to observe the working state of the rubidium clock; phase noise: output low phase Noise 10MHz signal; The important thing is Yijing's independent technology, and the specific parameters and extended functions can be customized.

We pursue these goals through technological innovation, listening to our customers, paying close attention to the welfare of our employees, supporting local communities, and minimizing our environmental impact.
MEMS Oscillator Frequency Stability The frequency output of all oscillators varies over temperature. This variation is a crucial performance specification that is expressed as frequency stability and measured in parts per million (PPM). This stability rating is inclusive of variation over temperature, voltage, process and soldering. 32 kHz Frequency Stability In terms of frequency stability revolutionary TempFlatTM MEMS 32 kHz oscillators are two times more accurate than quartz XTALs. The measured frequency variation of MEMS-based 32 kHz oscillators is plotted in blue lines as shown below. The red lines represent the frequency variation range of 32 kHz crystal resonators (XTALs). At room temperature(25 C), 32 kHz devices are trimmed to<10PPM, while quartz XTALs demonstrate 20PPM variation. Over the entire industrial temperature range, the devices exhibit < 75 to 100 PPM stability compared to typical quartz XTALs with - 160 to -200 PPM. With temperature compensation added, 32kHz TCXOs exhibit frequency stability well within their +5 PPM specification over temperature as shown below(Fig.9). The devices has achieved TCXO-level stability in a timing solution that consumes up to 50% less power and is up to 80% smaller than quartz-based solutions. MHz Oscillator Frequency Stability The frequency variation of standard AT cut quartz crystal oscillators is shown below(Fig.10), along with the stability of typical MEMS oscillators.Since revolutionary MEMS oscillators have built- in temperature compensation, these devices exhibit very flat frequency stability over the entire industrial temperature range, with adequate margin at the low and high temperatures to meet the specifications of high performance applications. 25 PPM XOs, as shown in the plot below(Fig.11),have better frequency stability characteristics compared to quartz 25 PPM XOs.
