Design Recommendations
To ensure optimal timing performance, place a 0.1μF ceramic decoupling capacitor between Vdd and GND near the crystal. PCB trace length between the oscillator IC and the crystal should be minimized to reduce noise and signal distortion. Keep crystal away from high-speed or high-power signal lines to avoid EMI and timing drift.
