• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing references
• Microcontroller clock sources

Oscillators Procurement Notes

Verify the specific suffix (OE vs PD) against the manufacturer's current datasheet to confirm voltage levels and pinout configurations, as variations exist within the 18QHTF21 series. Ensure the required operating temperature range aligns with the standard industrial specifications provided in the official documentation before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 39.2832 MHz reference is required with low-profile surface mounting constraints. The LVCMOS output is suitable for standard digital logic families. Consider the 3.3V supply requirement and verify that the 2.5x2.0mm footprint fits the PCB layout. Confirm enable/disable line availability in the system design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, including 1.8V and 3.3V variants. The 'OE' suffix typically denotes specific packaging or voltage characteristics distinct from other suffixes like 'PD' found in similar model numbers within the same product family.

Oscillators Replacement Considerations

Direct substitutes include other 39.2832 MHz XO components with identical 4-SMD no-lead footprints and LVCMOS outputs. Verify voltage compatibility (3.3V) and enable/disable pin functionality. Cross-reference with Mercury Electronics' own alternative models such as the 18QHTF21-39.315-OE if frequency tolerance allows.
