18QHTF21-26.66666-PD

Oscillators Overview

The 18QHTF21-26.66666-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 26.66666 MHz and utilizes an LVCMOS output interface. The device functions with a supply voltage of 1.8V and includes a standby or power-down control feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Standard XO configuration with LVCMOS output
• Integrated standby/power-down control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead footprint matches the PCB land pattern to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 26.66666 MHz reference. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6 mm package size for space-constrained designs where power-down functionality aids in extending battery life or reducing thermal output.
