18QHTF21-10.000135-OE

Overview

The 18QHTF21-10.000135-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 10.000135 MHz and utilizes LVCMOS output logic levels. The device is powered by a single 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface-mount assembly.

Feature Summary

• LVCMOS output interface
• Enable/Disable control functionality
• Compact 4-SMD no lead package

Applications

• General purpose clock generation
• Embedded system timing
• Consumer electronics

Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency tolerance and load capacitance requirements are met for your design. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a precise 10.000135 MHz reference is required in space-constrained applications. The LVCMOS output is compatible with standard digital logic families operating at 1.8V. Consider the enable pin if dynamic power saving is necessary during idle periods.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. Mercury has been a manufacturer of crystals and oscillators since 1973, establishing itself as a pioneer in Taiwan's quartz industry. This series represents their standard XO offerings.

Replacement Considerations

Direct substitutes include other 10.000135 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution.
