Pin Configuration

  • 20MHz Crystal Oscillator - (Pack of 10) Documentation
  • The 20MHz crystal oscillator is a quartz crystal resonator that provides a stable clock signal for microcontrollers, microprocessors, and other digital circuits. This component is commonly used in IoT devices, embedded systems, and other electronic applications. Here is a detailed explanation of the pins and how to connect them:
  • Pinout:
  • The 20MHz crystal oscillator has two pins:
  • Pin 1:
  • Pin Name: Pin 1 (or GND)
  • Description: Ground pin, connected to the ground plane of the circuit
  • Function: Provides a reference point for the oscillator circuit and helps to stabilize the crystal's oscillation
  • Pin 2:
  • Pin Name: Pin 2 (or OUT)
  • Description: Output pin, providing a 20MHz clock signal
  • Function: Outputs a stable, sinusoidal clock signal at a frequency of 20MHz, which can be used as an input to a microcontroller or other digital device
  • Connection Structure:
  • To connect the 20MHz crystal oscillator to a microcontroller or other digital device, follow these steps:
  • Step 1: Connect Pin 1 (GND) to the Ground Plane
  • Connect Pin 1 to a ground plane or a dedicated ground pin on the microcontroller or other digital device.
  • Ensure a solid electrical connection to prevent noise and interference.
  • Step 2: Connect Pin 2 (OUT) to the Clock Input
  • Connect Pin 2 to the clock input pin on the microcontroller or other digital device.
  • Make sure to match the clock signal frequency requirements of the device with the 20MHz output frequency of the crystal oscillator.
  • Additional Considerations:
  • When handling the crystal oscillator, take care to avoid physical stress, such as bending or soldering, which can damage the internal crystal structure.
  • Ensure proper power supply decoupling and noise filtering in the surrounding circuit to prevent electromagnetic interference (EMI) and noise from affecting the oscillator's performance.
  • For optimal performance, it is recommended to use a crystal oscillator with a load capacitance (CL) of 12-20 pF, depending on the specific application and microcontroller requirements.
  • Note: The above documentation is a general guide and may vary depending on the specific datasheet and application notes provided by the manufacturer. Always consult the datasheet and manufacturer's guidelines for specific connection and usage requirements.
