Crystal Oscillator 40MHz

The Crystal Oscillator 40MHz is a quartz crystal component that sets a precise and stable 40 MHz frequency. The quartz vibrates at its resonant frequency inside an oscillator circuit, giving a far more accurate and temperature-stable timing reference than a resistor-capacitor network. It is used as the clock source for microcontrollers, wireless chips and digital logic, both in new designs and in board repairs.

Crystal Oscillator 40MHz Specifications

• Frequency: 40 MHz
• Type: quartz crystal frequency reference
• Function: clock source for oscillator and timing circuits
• Polarity: none for two-pin crystals

Crystal Oscillator 40MHz Applications

• Clock source for chips that use a 40 MHz reference, such as the ESP32 Wi-Fi and Bluetooth SoC
• Wireless, RF and Wi-Fi module circuits
• FPGA, CPLD and digital logic clocks
• Replacing a faulty 40 MHz crystal on a circuit board
• Electronics labs and oscillator experiments

What's in the Box

• 1 × 40 MHz crystal oscillator

Tip: Place the crystal as close as possible to the chip's clock pins, with short traces and a solid ground around it. For a two-pin crystal, add the load capacitors recommended in the chip's datasheet; for a four-pin oscillator module, connect power and ground and take the clock from its output pin.
