18QHTF21-65.420-OE

Overview

The 18QHTF21-65.420-OE is a 65.42 MHz crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The component features an Enable/Disable control function via the OE suffix. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact surface-mount design suitable for space-constrained applications

Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics internal clocks

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout requirements to prevent assembly issues.

Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside precise 65.42 MHz timing. The LVCMOS output is suitable for standard logic families. Consider the enable pin if dynamic power saving or clock gating is necessary for the application.

Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products, including quartz crystals, oscillators, and filters. This part belongs to their series of surface-mount crystal oscillators designed for modern electronic devices requiring stable timing signals.

Replacement Considerations

Check for parts with identical 65.42 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package size. Verify pinout compatibility and electrical specifications before substitution.
