FAQ
Increase C1 and C2.
Decrease C1 and C2.
Equivalent Series Resistance. Lower ESR means easier startup and lower power consumption.
Power consumed during operation. Exceeding limits (e.g., >100μW) may damage the crystal.
Add a damping resistor (Rd) at the inverter output.
No, they rely on the MCU’s internal oscillator circuit.
Yes, typically 0.1μF near VCC to reduce noise.
Parts per million. ±10ppm means 10Hz deviation per 1MHz.
Place the crystal close to MCU pins with short traces.
To reduce interference from high-speed signals.
Avoid them as they introduce parasitic effects.
Yes, for impedance symmetry.
