Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system requirements. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check for any specific handling instructions regarding electrostatic discharge sensitivity during assembly and storage processes.

Oscillators Selection Notes

Select this component when a 24.91 MHz clock source is required with low power consumption capabilities. The LVCMOS interface is suitable for standard digital logic families. Consider the small form factor for space-constrained designs. Verify compatibility with the host controller's input voltage levels and ensure the operating temperature range meets environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 2.0x1.6 mm package. The series provides options for different clock speeds while maintaining consistent electrical characteristics and pin configurations. The 'PD' suffix indicates the inclusion of power-down control features, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 24.91 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal performance. Cross-reference with other manufacturers offering similar MEMS or crystal oscillators in the same footprint if Mercury Electronics parts are unavailable.
