18QHTF21-11.70388-OE

Overview

The 18QHTF21-11.70388-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.70388 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control capability
• Compact 4-SMD no-lead surface mount package design

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the OE suffix with manufacturer documentation to confirm any specific ordering or packaging variations.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for power-sensitive designs. Consider the small form factor for space-constrained boards. Verify temperature range specifications if operating in extreme environments, as general data may not cover all variants.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series typically offers standard oscillators with various frequencies and voltage levels. Mercury has decades of experience in crystal manufacturing, providing reliable timing solutions for industrial and consumer electronics markets.

Replacement Considerations

Direct substitutes must match the 11.70388 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check pinout compatibility and electrical characteristics such as phase noise and jitter. Consult distributor databases for cross-references from other manufacturers offering equivalent surface-mount oscillators.
