Abracon recommends a symmetrical layout with the crystal oscillator placed near the center of the PCB, with minimal routing and no vias under the component. A ground plane under the component is also recommended.
Ensure the power supply is stable and has a low noise floor. Also, add a 10-100nF decoupling capacitor between VCC and GND near the oscillator. A slow power-up ramp can also help.
The ASFLMB-33.333MHZ-XY-T has a frequency tolerance of ±20 ppm over the operating temperature range. This means the frequency can deviate by up to ±6.67 Hz from the nominal 33.333 MHz frequency.
While the ASFLMB-33.333MHZ-XY-T is designed to be rugged, it's still a crystal oscillator and may not perform well in extremely high-vibration environments. Consider using a more robust oscillator or additional vibration dampening measures if necessary.
Follow standard ESD handling procedures when handling the ASFLMB-33.333MHZ-XY-T. Use an ESD wrist strap or mat, and ensure the PCB is properly grounded during assembly and testing.
