Oscillators Procurement Notes

Verify the exact operating temperature range and load capacitance requirements against the specific application design before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead footprint matches the PCB layout constraints. Cross-reference the datasheet for any specific handling or soldering recommendations associated with this package type.

Oscillators Selection Notes

Select this component when a precise 37.209375 MHz clock source is required for low-voltage digital circuits. The choice depends on the necessity for LVCMOS outputs and the availability of a 1.8V power supply. Consider the physical space constraints due to the small SMD form factor. Evaluate if the standby feature provides sufficient power management benefits for the intended use case compared to continuous operation alternatives.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar package footprints. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from always-on variants. This places the component within the broader category of precision timing devices used in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators from Mercury Electronics with identical 37.209375 MHz frequency and 4-SMD no-lead packages. Verify pinout compatibility and electrical specifications before swapping. Alternative manufacturers may offer equivalent performance but require careful verification of package dimensions and output drive strength.
