• Enable/Disable control functionality
• Wide supply voltage compatibility

Oscillators Applications

• Embedded systems requiring precise clock signals
• Industrial control equipment
• Consumer electronics devices

Oscillators Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm voltage or tolerance variations compared to other variants like 'B'. Ensure the operating environment stays within the specified -40°C to +85°C range. Confirm pinout compatibility with the target PCB footprint before integration.

Oscillators Selection Notes

Select this model when a 21.4 MHz CMOS clock source with low power consumption is required. The enable/disable feature allows for dynamic power management in battery-operated applications. Consider the ±20 ppm stability for general timing needs rather than high-precision synchronization tasks.

Oscillators Part Context

This part belongs to the SX7M series of surface-mount oscillators from Shenzhen SCTF Electronics. The series offers various frequencies and packages, designed for space-constrained electronic designs. The 4-SMD form factor facilitates automated assembly processes.

Oscillators Replacement Considerations

Cross-reference with SX7M21.400B20F30TNN if voltage levels differ. Verify pin-to-pin compatibility with existing designs before substitution.
