The recommended land pattern for AS-8.000-20-SMD-TR is a rectangular pad with a size of 1.5mm x 0.8mm, with a non-solder mask defined (NSMD) pad shape.
To minimize the impact of vibration and shock on the crystal, it's recommended to use a shock-absorbing material, such as a silicone adhesive, to mount the crystal to the PCB. Additionally, ensure the PCB is properly secured to the device or enclosure.
Store the AS-8.000-20-SMD-TR in a dry, cool place, away from direct sunlight and moisture. The recommended storage temperature range is -20°C to 40°C, with a relative humidity of 60% or less.
While the AS-8.000-20-SMD-TR is rated for operation up to 85°C, it's not recommended for use in high-temperature environments above 85°C. Prolonged exposure to high temperatures can affect the crystal's frequency stability and overall performance.
To ensure frequency stability, it's essential to follow proper PCB design and layout guidelines, including using a low-ESR capacitor and a stable voltage supply. Additionally, consider using a crystal oscillator with a built-in PLL or a frequency synthesizer to minimize frequency drift.
