Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD package footprint matches the PCB layout constraints. Check for any specific environmental ratings if the application involves extreme temperatures.

Oscillators Selection Notes

Select this component when a 15.367 MHz reference is required for LVCMOS-compatible circuits. The 1.8V operating voltage makes it suitable for modern low-power applications. Consider the physical size of the 2.00mm x 1.60mm package for space-constrained designs. Evaluate the need for a power-down feature to extend battery life in portable devices.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies tailored for different timing needs. The 'PD' suffix typically indicates the inclusion of a power-down control pin, allowing for active and inactive states. These oscillators are designed for reliability in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 15.367 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent frequency stability and phase noise specifications. Ensure the replacement supports the same standby functionality. Cross-reference with other manufacturers offering similar SMD XO packages.
