18QHTF21-13.5672-OE

Overview

The 18QHTF21-13.5672-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 13.5672 MHz with an LVCMOS output logic level. The device requires 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 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable and disable control functionality
• Utilizes a small form factor SMD package without leads

Applications

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

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 guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 13.5672 MHz timing source is required for 1.8V logic applications. The choice depends on the need for an enable/disable pin to manage power consumption or system state. Consider the physical size constraints of the 2.0x1.6mm package relative to available board space and thermal management needs.

Part Context

This part belongs to the Mercury Electronic XO series, which provides standard frequency oscillators. The model number indicates a 13.5672 MHz frequency variant within the 18QHTF21 family. These components are designed for surface-mount technology, offering reliability for mass production environments requiring stable clock signals.

Replacement Considerations

Direct substitutes include other 13.5672 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify electrical parameters such as supply voltage and output swing. Check mechanical dimensions to ensure fitment. Cross-reference specifications for phase noise and jitter if high precision is required.
