Oscillators Procurement Notes

Verify the specific voltage variant required for your design, as the SX3M series includes 1.8V, 3.3V, and 5V options distinguished by suffix codes. Confirm that the 4-SMD no-lead footprint matches your PCB land pattern. Ensure the selected model meets the thermal requirements of your intended operating environment. Cross-reference the manufacturer datasheet for detailed soldering profiles and reflow temperature limits to guarantee reliable attachment during manufacturing.

Oscillators Selection Notes

Choose this component when a 74.25 MHz reference is necessary for digital interfaces or video pipelines. The CMOS output level simplifies interfacing with standard logic families without additional buffering. Consider the enable/disable feature if system power efficiency is a priority. Evaluate the ±30ppm stability against your system's jitter budget. Verify that the 5V supply aligns with your board's available voltage rails before finalizing the bill of materials.

Oscillators Part Context

This oscillator belongs to the SX3M series of surface-mount crystal oscillators. The series offers various voltage options and frequencies tailored for consumer electronics and industrial applications. The specific model provides a balance between performance and size. It serves as a critical timing source for microcontrollers and data converters. The standardized package ensures compatibility with common pick-and-place equipment used in modern electronics manufacturing.

Oscillators Replacement Considerations

Direct substitutes must match the 74.25 MHz frequency, CMOS output type, and 4-SMD package. Voltage variants such as SX3M74.250B20F30TNN (3.3V) or SX3M74.250D20F30TNN (1.8V) are electrically incompatible due to different supply requirements. Only replace with identical part numbers or verified equivalents from the same manufacturer family.
