18QHTF21-10.695-OE

Overview

The 18QHTF21-10.695-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 10.695 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 suitable for surface mount applications.

Feature Summary

• Standard XO configuration with LVCMOS output logic
• Integrated enable and disable functionality
• RoHS compliant construction

Applications

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

Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm exact pinout and electrical tolerances. Ensure compatibility with 1.8V logic levels and check MSL rating for soldering reflow profiles. Confirm RoHS status matches project requirements before finalizing procurement orders.

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. Verify that the 10.695 MHz frequency aligns precisely with the target system clock requirements and that enable/disable control is necessary for power management.

Part Context

This part belongs to the QHTF series of standard oscillators from Mercury Electronics. The manufacturer has produced frequency control products since 1973 and is recognized as a pioneer in the Taiwan quartz industry. This series typically includes various frequencies and voltage options within similar SMD packages.
