Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required tolerance and temperature range specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Ensure the selected variant supports the necessary 3.3V logic levels and CMOS output swing requirements for the intended application circuitry.

Oscillators Selection Notes

Select this oscillator when a 21.4 MHz reference signal is required with low profile packaging. Consider the CMOS output type for direct interfacing with microcontrollers or digital processors. Evaluate the enable/disable feature against system power management strategies to determine if active control is necessary for energy efficiency during idle periods.

Oscillators Part Context

This component belongs to the series of standard crystal oscillators produced by Shenzhen SCTF Electronics. These devices provide stable frequency generation for digital systems. The SX7M21.400B10F20TNN specifically addresses applications needing a fixed 21.4 MHz clock source in a small form factor, distinguishing it from larger through-hole or wider frequency range alternatives.

Oscillators Replacement Considerations

Cross-reference with other 21.4 MHz CMOS oscillators in 4-SMD packages. Verify pinout compatibility and electrical characteristics such as supply voltage and output swing before substitution. Ensure thermal and mechanical specifications match the original design requirements.
