18QHTF21-25.750-OE

Oscillators Overview

The 18QHTF21-25.750-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.75 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. 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 and disable functionality for power management
• Surface-mount 4-SMD no lead package design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific part number suffix against official Mercury Electronics documentation to ensure correct frequency and package configuration. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Check for any specific handling instructions related to the no-lead SMD package during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for space-constrained designs. The 4-SMD no lead package offers a small footprint suitable for high-density PCB layouts. Ensure the application does not require spread spectrum or additional jitter reduction features beyond standard specifications.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage crystal oscillators. The series typically supports various frequencies within the LVCMOS format. The 25.75 MHz variant provides a specific timing solution for systems needing this exact clock rate with minimal power consumption.

Oscillators Replacement Considerations

Direct substitutes must match the 25.75 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and electrical characteristics with alternative manufacturers if cross-referencing is necessary.
