18QHTF21-13.507-OE

Overview

The 18QHTF21-13.507-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.507 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features 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.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct frequency and package configuration. Confirm that the LVCMOS output type and 1.8V supply voltage align with target circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-profile 4-pin SMD oscillator is required for 13.507 MHz applications. Ensure the design accommodates the 1.8V operating voltage and LVCMOS logic levels. Verify thermal and mechanical constraints for the no-lead package within the assembly process.

Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and package types. The 18QHTF21 designation indicates a specific form factor within their standard oscillator lineup, distinct from TCXOs or VCXOs.

Replacement Considerations

Direct substitutes must match the 13.507 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Cross-reference with other manufacturers offering identical pinout and electrical specifications.
