Oscillators Procurement Notes

Verify the specific suffix 'A' against the datasheet to confirm the 5V supply requirement, as other variants may differ. Ensure the ordering code matches the exact frequency tolerance and temperature range specifications required for the target application environment. Cross-reference the manufacturer's latest documentation to confirm current production status and availability before finalizing procurement plans.

Oscillators Selection Notes

Select this component when a precise 1.544 MHz reference is needed for digital interfaces requiring CMOS logic levels. The 5V supply voltage makes it suitable for legacy or specific industrial designs not utilizing lower voltage rails. Consider the ±20 ppm stability for applications where moderate precision is sufficient. The wide temperature range supports operation in demanding environmental conditions without additional thermal management.

Oscillators Part Context

This oscillator belongs to the SX7M series from Shenzhen SCTF Electronics, which provides various standard frequency options in compact surface-mount packages. The series is designed for general-purpose clocking needs in electronic assemblies. The specific model integrates the quartz resonator and oscillator circuit into a single sealed unit, simplifying PCB layout compared to discrete crystal solutions.

Oscillators Replacement Considerations

Direct substitutes include the SX7M1.544D10F20TNN variant, though verification of the supply voltage difference (1.8V vs 5V) is mandatory. Other models within the SX7M family sharing the same footprint and frequency may be compatible if electrical parameters align. Always validate pinout compatibility and electrical characteristics before substitution.
