Oscillators Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Procurement should focus on verifying stock availability through authorized distributors or secondary market suppliers. Buyers must confirm the authenticity of available units and review datasheet revisions prior to purchase, as production has ceased. Design-in verification is critical due to potential supply chain constraints associated with discontinued part numbers.

Oscillators Selection Notes

Engineers selecting this part should verify that the 74.250 MHz frequency and ±25ppm stability meet system timing requirements. The 3.3V logic level and CMOS output must be compatible with the receiving circuitry. The enable/disable feature offers power management flexibility. Given the obsolete status, alternative sourcing strategies or redesign considerations may be necessary if long-term supply continuity is required.

Oscillators Part Context

The TC series represents TXC Corporation's line of miniature MEMS oscillators designed for surface-mount applications. This specific model falls within the standard XO category, offering a balance between performance and size. The 4-SMD no-lead package facilitates automated assembly processes. TXC Corporation specializes in frequency products, leveraging MEMS technology to replace traditional quartz crystals in various consumer and industrial devices.

Oscillators Replacement Considerations

As the TC-74.250MBD-T is obsolete, direct replacement requires checking for updated series from TXC or cross-referencing with other manufacturers offering identical 74.250MHz MEMS oscillators in 4-SMD packages with similar electrical specifications.
