Frequently Asked Questions
What load capacitance and drive level does the LFXTAL003240 require for oscillator circuit design?
The LFXTAL003240 specifies a 30 pF load capacitance and a 500 µW maximum drive level. To achieve this load capacitance in a typical parallel resonant circuit, each external load capacitor should be approximately 50 pF to ground, adjusting for PCB stray capacitance of around 5 pF, to ensure stable 16 MHz oscillation within the 30 ppm tolerance band.
How does the 5 ppm/year aging rate of the LFXTAL003240 affect long-term frequency accuracy in deployed systems?
With a 5 ppm/year aging rate and an initial 30 ppm tolerance, the LFXTAL003240 nominally drifts up to 5 ppm per year from its calibrated 16 MHz output. After 5 years in service, cumulative aging could add 25 ppm of drift—still within acceptable bounds for UART, SPI, and I2C interfaces in non-GPS industrial embedded systems.
For which prototype and production scenarios is the HC49/4H through-hole package of the LFXTAL003240 preferred over SMD crystal alternatives?
The LFXTAL003240 in its HC49/4H 2-pin through-hole package is preferred for prototype boards, hand-soldered low-volume production, and designs where mechanical robustness under vibration is critical. Through-hole mounting provides stronger PCB anchoring than 3.2 x 2.5 mm SMD crystals, making it suitable for industrial field equipment and ruggedized embedded controllers.
