18QHTF21-14.745-OE

Oscillators Overview

The 18QHTF21-14.745-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.745 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable pin functionality
• Utilizes a leadless surface-mount package design

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application environment before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints to avoid assembly issues.

Oscillators Selection Notes

Select this component when a precise 14.745 MHz timing source is required for low-power applications. The choice is driven by the need for LVCMOS compatibility and the physical constraint of a 4-SMD no-lead package. Consider the enable/disable feature if power management during idle states is necessary for the design.
