18QHTF21-30.780-OE

Oscillators Overview

The 18QHTF21-30.780-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 30.78 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Surface-mount 4-SMD no lead package design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and package configuration. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any specific handling instructions related to the no-lead SMD package during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management in battery-operated devices. Ensure the 4-SMD footprint matches the PCB layout constraints and that the 30.78 MHz frequency meets the system timing specifications.

Oscillators Part Context

This model belongs to the Mercury Electronics standard XO series, which provides reliable quartz-based timing solutions. The company has extensive experience in frequency control products, offering various oscillator types including TCXO and VCXO. This specific part represents a standard fixed-frequency option within their portfolio.

Oscillators Replacement Considerations

Direct substitutes must match the 30.78 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics before substitution. Consult the manufacturer's cross-reference list for approved alternative part numbers.
