Oscillators Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm voltage and tolerance specifications. Ensure that the ordering information matches the required frequency tolerance and stability parameters for the target application environment. Cross-reference the package dimensions and pin configuration with the mechanical drawings provided in the datasheet to guarantee correct footprint compatibility during PCB layout and assembly processes.

Oscillators Selection Notes

Select this component when a 29.4989 MHz CMOS clock source with enable/disable capability is required. Consider the ±20ppm tolerance and ±30ppm stability limits relative to system timing requirements. Evaluate the 1.62V to 3.63V supply range against available power rails. Confirm that the SMD package dimensions fit within the designated board space constraints and thermal management guidelines for the intended operating temperature range.

Oscillators Part Context

This oscillator belongs to the SX7M series from Shenzhen SCTF Electronics, designed for wide-voltage applications. The series typically offers CMOS outputs in compact SMD packages suitable for space-constrained designs. Variants within this family share similar form factors but differ in frequency, voltage ranges, and tolerance specifications, necessitating careful selection based on exact electrical requirements.

Oscillators Replacement Considerations

Direct substitutes include other SCTF SX7M series oscillators with matching 29.4989 MHz frequency and compatible voltage ranges.
