18QHTF21-86.613-PD

Overview

The 18QHTF21-86.613-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 86.613 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V. The device features a standby or power-down mode for energy management. It is housed in a compact 4-SMD, no lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Standard XO configuration with LVCMOS output interface
• Integrated standby and power-down functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design 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 datasheet to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a stable 86.613 MHz clock source is required with low power consumption capabilities. The LVCMOS output is compatible with standard digital logic families. Consider the 1.8V operating voltage constraint and the need for power-down control in battery-operated or energy-sensitive designs. The small form factor makes it suitable for space-constrained printed circuit board layouts.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series offers various frequencies within the standard XO category. Mercury Electronics specializes in quartz crystals and frequency control products, providing reliable timing solutions for electronic systems. This specific model represents a fixed-frequency option within their broader portfolio of clock generators.

Replacement Considerations

Direct substitutes must match the 86.613 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Cross-reference with other manufacturers offering similar SMD oscillators if availability is an issue, ensuring all functional parameters remain identical.
