18QHTF53-42.336-OE

Oscillators Overview

The 18QHTF53-42.336-OE is a quartz crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 42.336 MHz with an LVCMOS output logic level. The device functions on a supply voltage of 1.8V and features an active enable/disable control pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0mm x 3.2mm.

Oscillators Feature Summary

• Integrates an enable/disable function for power management via a dedicated control pin
• Delivers standard LVCMOS output signals suitable for digital logic interfaces
• Utilizes a leadless surface-mount package design for automated assembly

Oscillators Applications

• Clock signal generation for embedded systems
• Timing reference for communication modules
• Synchronization circuits in consumer electronics

Oscillators Procurement Notes

Verify the specific suffix 'OE' confirms the presence of the enable/disable functionality as distinct from standard variants. Ensure the operating temperature range meets the target application requirements. Confirm the package footprint matches the PCB layout constraints for the 5.0x3.2mm SMD form factor before finalizing component selection.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside precise clock timing. The enable feature allows for dynamic power control during idle states. Consider the 42.336 MHz frequency against system clock dividers to ensure compatibility with downstream digital logic levels and interface standards.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which includes various frequencies and package types. The 18QHTF53 prefix indicates a specific family of surface-mount oscillators. The '-OE' suffix specifically denotes the inclusion of an output enable pin, differentiating it from constant-output counterparts within the same physical package.

Oscillators Replacement Considerations

Direct substitutes include other 42.336 MHz LVCMOS oscillators with identical 1.8V operation and enable pins. Verify pinout compatibility and thermal characteristics when cross-referencing with alternative manufacturers offering similar 5.0x3.2mm packages.
