Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout configuration and electrical characteristics. Ensure the supply voltage matches the required 3.3V specification. Confirm that the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Oscillators Selection Notes

Select this component when a fixed 40 MHz frequency is required with CMOS output levels. Consider the ±30ppm stability rating for timing accuracy needs. Evaluate the 4-SMD package dimensions against available PCB real estate. Compare performance against alternative models like the M-series if wider voltage input ranges are necessary.

Oscillators Part Context

This model belongs to the SX2M series of standard oscillators from Shenzhen SCTF Electronics. The series provides reliable clock signals for various electronic circuits. The B-series designation typically indicates specific voltage and tolerance configurations within the product line, distinguishing it from other variants offering different voltage inputs or packaging options.

Oscillators Replacement Considerations

The SX2M40.000M20F30TNN serves as a related variant within the same series. It offers a wider input voltage range of 1.62V to 3.63V compared to the fixed 3.3V requirement of the TNF model. Verify pin compatibility and output drive strength before substituting.
