Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when ordering. Confirm that the 'J' variant aligns with the required -40°C to 105°C temperature range rather than extended ranges. Ensure the 3.3V supply requirement matches the target circuit design. Check for AEC-Q100 certification requirements if deploying in automotive environments. Validate the 4-SMD no-lead package dimensions against PCB layout constraints.

Selection Notes

Select this model when an automotive-certified oscillator is required for space-constrained designs. The 25 MHz frequency suits standard communication and processing interfaces. Consider the 22mA current draw for battery-powered or low-power applications. The enable/disable feature allows for dynamic power optimization. Verify compatibility with 3.3V logic levels before integration into the system architecture.

Part Context

This component belongs to the QTM216 series of low EMI CMOS oscillators from QST. The series includes various frequencies and temperature grades. The J suffix typically denotes the -40°C to 105°C industrial/automotive grade. Similar parts include QTM216E variants which may differ in temperature range or specifications. The 2.0x1.6mm size is common for high-density surface-mount applications.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 3.3V supply, and 4-SMD package. Verify AEC-Q100 compliance if automotive use is mandatory. Compare pinout configurations to ensure electrical compatibility. Check if alternative manufacturers offer equivalent jitter and phase noise performance.
