18QHTF21-33.968-OE

Oscillators Overview

The 18QHTF21-33.968-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 33.968 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an enable/disable control interface. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interfacing
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing references
• Consumer electronics clock generation

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm enable/disable functionality versus other variants like PD. Ensure the 1.8V supply requirement matches the target circuit design. Confirm the 4-SMD no-lead footprint dimensions align with PCB layout constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 33.968 MHz reference is required with low voltage operation. The enable/disable feature allows for dynamic power control in battery-operated devices. Verify compatibility with LVCMOS input thresholds of downstream logic gates to ensure signal integrity across the operating temperature range.

Oscillators Part Context

This part belongs to the Mercury Electronic XO series, which includes various frequencies and package types. The 18QHTF21 series typically offers standard performance levels suitable for general-purpose timing applications. Different suffixes indicate variations in control modes or packaging formats within the same frequency family.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-33.968-PD if standby functionality is acceptable instead of enable/disable. Other Mercury parts in the 18QHTF21 series may serve as alternatives if frequency and package compatibility are maintained.
