Procurement Notes

Verify the manufacturer designation carefully, as sources list both TXC Corporation and QST for this part number. Confirm the specific suffix matches the required voltage and stability specifications. Ensure the package type aligns with PCB footprint requirements. Cross-reference the datasheet for exact pinout definitions before integration.

Selection Notes

Select this component when a 50 MHz CMOS clock source is required in a small form factor. Consider the ±50ppm stability limit for applications tolerant of moderate drift. Verify that the 2.5V supply voltage matches the target system logic levels. Check the operating temperature range against environmental conditions.

Part Context

This oscillator belongs to the QTM532 series, which offers various frequency options in a standardized 5.0x3.2mm SMD package. The series provides solutions for digital timing needs across consumer and industrial electronics. Variants differ primarily in frequency, output type, and stability ratings while maintaining consistent physical dimensions.

Replacement Considerations

Direct substitutes include other 50MHz CMOS oscillators in 5.0x3.2mm packages from manufacturers like TXC or Abracon. Ensure replacement parts match the 2.5V supply requirement and ±50ppm stability. Verify pin compatibility and electrical characteristics before substitution.
