18QHTF21-2.5396-OE

Oscillators Overview

The 18QHTF21-2.5396-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 2.5396 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• LVCMOS output logic interface
• Enable and disable control functionality
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 2.5396 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 for any specific environmental or reliability certifications if required for the application.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required. The LVCMOS output is suitable for standard digital logic interfaces. The small 2.0x1.6 mm package is ideal for space-constrained designs. Consider the enable/disable feature if power efficiency during idle states is a priority.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical package. The series provides standard XO solutions with LVCMOS outputs. Other variants in the family share identical electrical characteristics and packaging but differ in nominal frequency specifications.

Oscillators Replacement Considerations

Direct substitutes must match the 2.5396 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pin compatibility and thermal requirements before substitution.
