    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

    SJK Invites You to Electronic Asia 2023 Hong Kong

    Electronic Asia 2023 International Electronic Components and Manufacturing Technology Exhibition will be held on October 13-16, 2023 in Hong Kong Convention and Exhibition Center.Located in One Expo Drive, Wanchai, Hong Kong (Harbour Road Entrance), our Hong Kong delegation will participate in this exhibition, our Booth No.: 5B-C35, we will exhibit... 06/09/2023

    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
