The device requires a supply voltage of 1.8V and features a standby or power-down mode for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Supports standby and power-down modes for reduced power consumption
• Utilizes LVCMOS output logic for digital interface compatibility
• Housed in a 4-SMD, No Lead surface-mount package

Applications

• Digital signal processing systems requiring precise clock timing
• Communication equipment utilizing standard frequency references
• Embedded systems with low-voltage logic requirements

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply voltage aligns with the system's power rails. Confirm that the 4-SMD, No Lead package dimensions fit within the available PCB space. Cross-reference the part number suffix to ensure the correct packaging and specifications are obtained from the manufacturer.

Selection Notes

Select this component when a stable 86.14 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage constraint during power budgeting. Evaluate the need for standby functionality if power efficiency is critical. Compare the physical footprint of the 4-SMD package against other available oscillator options to ensure mechanical compatibility.

Part Context

This model belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage levels. The 'PD' suffix likely indicates specific packaging or testing parameters defined by the manufacturer. This component serves as a fundamental timing source for electronic devices requiring accurate clock signals.

Replacement Considerations

Direct substitutes must match the 86.14 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD package. Check for equivalent standby functionality. Consult manufacturer cross-reference lists for verified alternatives.
