18QHTF21-65.0159-OE

Overview

The 18QHTF21-65.0159-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 65.0159 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports active enable and disable control functions for power management
• Delivers LVCMOS output logic levels for digital interface compatibility
• Utilizes a leadless SMD package design for automated assembly

Applications

• Embedded systems requiring precise clock synchronization
• Consumer electronics with low-voltage logic interfaces
• Industrial control modules utilizing standard crystal oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the Enable/Disable pin functionality is integrated into your firmware or hardware control scheme to manage power states effectively during operation.

Selection Notes

Select this component when a 65.0159 MHz reference signal is required within a 1.8V logic environment. The choice is appropriate for designs prioritizing low-profile surface-mount packaging. Consider the Enable/Disable feature if dynamic power saving is necessary. Verify that the LVCMOS output swing matches the input thresholds of the downstream receiving components to ensure reliable signal integrity.

Part Context

This part belongs to the 18QHTF series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix indicates the presence of an output enable function. This specific model provides a fixed frequency solution for timing applications where size constraints and low voltage operation are critical design parameters.

Replacement Considerations

Direct substitutes must match the 65.0159 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter before swapping. Consult manufacturer cross-reference lists for equivalent parts with identical form factors and functional characteristics.
