18QHTF21-73.66979-OE

Overview

The 18QHTF21-73.66979-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 73.66979 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

LVCMOS output logic for digital interface compatibility
Integrated enable/disable pin for power control
Compact 4-SMD no-lead surface mount package

Applications

General clock signal generation for digital circuits
Timing reference for microprocessors and FPGAs
Embedded systems requiring stable frequency sources

Procurement Notes

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

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 battery-powered or power-sensitive designs. Consider the specific 73.66979 MHz frequency requirement and the physical constraints of the 4-SMD package during the design phase.
