18QHTF21-63.8975-OE

Overview

The 18QHTF21-63.8975-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 63.8975 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable and disable control capabilities
• Utilizes a leadless SMD package for surface mounting

Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics timing

Procurement Notes

Verify the specific frequency suffix matches the required 63.8975 MHz specification. Confirm the 1.8V operating voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint is compatible with the PCB layout. Check datasheet details for thermal and electrical limits before integration.

Selection Notes

Select this component when a 63.8975 MHz LVCMOS clock source is required. The 1.8V supply voltage suits low-power digital systems. The enable/disable feature allows for power management. The small form factor is suitable for space-constrained designs.
