Oscillators Procurement Notes

Verify that the ordering suffix matches the required specifications, specifically the B20F30 designation which indicates the tolerance and load conditions. Confirm the package type corresponds to the 7050-4P SMD footprint. Ensure the supply voltage requirements align with the 1.62V to 3.63V operational range before integration into the design.

Oscillators Selection Notes

Select this component when a 40 MHz reference is required for CMOS-based digital circuits. Consider the ±20 ppm stability for applications needing tight frequency accuracy. The enable feature makes it suitable for battery-powered devices where power conservation during idle states is critical. Verify the operating temperature range meets the environmental constraints of the final assembly.

Oscillators Part Context

This part belongs to the SX7M series of surface-mount crystal oscillators from Shenzhen SCTF Electronics. The series offers various frequencies and packages, with the SX7M40.000B20F30TNN representing a specific 40 MHz configuration. It is designed as a drop-in replacement for other standard 40 MHz XO components in similar SMD footprints, provided electrical parameters match.

Oscillators Replacement Considerations

Direct substitutes include the SX7M40.000M20F30TNN variant, which shares the same frequency and package but may differ in specific tolerance or load characteristics. Cross-reference with other 40 MHz CMOS oscillators in the 7050-4P package, ensuring voltage and enable pin functionality are compatible.
