    OCXO Constant Temperature Crystal Oscillator Product Introduction

    An OCXO (Oven Controlled Crystal Oscillator) is a type of crystal oscillator that maintains a constant temperature using an oven, minimizing frequency changes due to environmental temperature fluctuations, resulting in greater frequency stability.However, the oven requires continuous operation, leading to longer startup times compared to XO and TCX... 15/11/2024

    AT-cut and SC-cut Crystal Differences

    After the growth of quartz crystal blanks is completed, these are cut into quartz crystals of different sizes and thicknesses. However, quartz crystals have different performance characteristics when cut in different types. Among them, AT cutting and BT cutting are commonly used in resonator and oscillator products, while SC cutting are commonly us... 01/11/2024

    Relevant Standards for Quartz Crystals

            In today's rapidly developing technology, quality and service have become the core elements of enterprise competition. We are pleased to announce that Shenzhen Crystal Technology Industrial, as a leading enterprise in the crystal oscillator industry, has been deeply involved in the crystal oscillator industry fo... 31/10/2024

    Where are Quartz Crystals used?

    Crystal Resonators and Oscillators are well known for their use in applications demanding precise and stable frequency, or accurate timing (if you are a time-domain person).Below you can see a list of the main fields and the role they play in them.  PCBs where Crystals are used: 1 Microcontroller, 2 Transceiver, 3 Vehicle ECU, 4 Sinthesizer, 5... 29/02/2024

    Where are Crystals used?

    DSP (Digital Signal Processing) Passive crystal oscillators require the assistance of a DSP (Digital Signal Processing) master chip oscillator to generate an oscillation circuit. In general, passive crystal oscillators need to be matched with external capacitors for use. The accuracy of output frequency is related to the matching of external c... 07/06/2023

    Size Matters

    Miniaturization is a popular trend in modern electronic products, from smart wearables, electronic mobile devices to smart homes, these practical cases in daily life can be described as countless.Therefore, most electronic manufacturers hope to purchase smaller components, including frequency components - crystal oscillators.So, what impact will a ... 07/06/2023

    Temperature Range

    Below are the most common working temperature range for our Crystal Resonators and Oscillators:Extended Commercial: -20 to +85ºCIndustrial: -40 to +85ºCAutomotive: -40 to +105ºCFull-Range Industrial: -40 to +125ºC... 06/06/2023

    External Capacitor Dependance

    Firstly, it should be noted that any crystal oscillator that requires an external capacitor is a passive crystal oscillator. Additionally, note that distinguishing between external capacitors C1 and C2 (ground capacitance, ground capacitance) is not equivalent to crystal oscillator load capacitance (CL). C1 and C2 are the total capacitance values o... 06/06/2023

    Design Considerations

    Three aspects to take into consideration when designing an oscillator circuit are mentioned below:1. Drive Level Applying excessive drive level to the crystal units may cause deterioration of characteristics or damage. Circuit design must be such as to maintain a proper drive level.2. Negative Resistance Unless adequate negative resistanc... 06/06/2023

    Large Frequency Deviation

    What should I do if the frequency deviation of the crystal oscillator is too large? There are two types of crystal oscillator application solutions: active crystal oscillator solutions and passive crystal oscillator solutions.Active crystal oscillator:If the frequency deviation of the active crystal oscillator is too large, please choose an ac... 06/06/2023
