Oscillators Procurement Notes

Verify the specific suffix against official Mercury Electronics documentation to confirm electrical characteristics and pinout configuration. Ensure the selected variant matches the required supply voltage and output logic levels for the target application circuit design.

Oscillators Selection Notes

Select this component when a small form factor is required alongside standard LVCMOS compatibility. Consider the ±50ppm stability specification relative to system timing requirements. Verify that the 1.8V supply voltage aligns with the host system's power rails before integration.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronic. The series provides various frequency options within a standardized footprint, allowing designers to maintain consistent board layouts across different product variants while adjusting only the frequency parameter.

Oscillators Replacement Considerations

Direct substitutes include other 4.096 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers, provided they match the 1.8V supply and enable pin functionality.
