Crystal Oscillators Design Consideration Information
Choosing a Crystal
Printed Circuit Board (PCB)
When choosing a crystal for the 32768 Hz Slow Clock Oscillator or for the 3-20 MHz Oscillator,
several parameters must be taken into account. Important parameters between crystal and
SAM3U specifications are as follows:
SAM3U Oscillators are low power oscillators requiring particular attention when designing PCB
systems. A board design example is given on Atmel’s website in the MCU Technical Center
Section.
• Load Capacitance
• Drive Level
• Equivalent Series Resistor (ESR)
• Shunt Capacitance
– This is the equivalent capacitor value the oscillator must “show” to the crystal in
– Crystal drive level >= Oscillator Drive Level. Having a crystal drive level number
– Crystal ESR <= Oscillator ESR Max. Having a crystal with ESR value higher than
– Max. crystal Shunt capacitance <= Oscillator Shunt Capacitance (
order to oscillate at the target frequency. Crystal must be chosen according to the
internal load capacitance (C
load capacitance will result in a frequency drift.
lower than the oscillator specification may damage the crystal.
the oscillator may cause the oscillator to not start.
Having a crystal with ESR value higher than the oscillator may cause the
oscillator to not start.
