Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official mechanical drawing. Check RoHS compliance status if environmental regulations apply to the end product.

Oscillators Selection Notes

Select this component when a precise 28.376 MHz timing source is required with low power consumption capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if power management during idle states is a critical design requirement. Evaluate the small form factor against available board space constraints.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized package outline. The 'OE' suffix likely denotes a specific ordering or packaging variant, though functional characteristics remain consistent with the base model specifications defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes may include other 28.376 MHz LVCMOS oscillators in 4-SMD packages from different manufacturers. Verify pinout compatibility and electrical parameters such as current consumption and output swing before substitution. Cross-reference with Mercury Electronics' own alternative frequencies if exact matching is not feasible.
