18QHTF21-26.736-PD

Oscillators Overview

The 18QHTF21-26.736-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 26.736 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Integrates a standby mode to reduce power consumption during inactive periods
• Utilizes LVCMOS output interface for digital signal compatibility
• Designed in a small form factor surface-mount package

Oscillators Applications

• Embedded systems requiring precise clock timing
• Portable electronic devices utilizing low voltage operation
• Digital communication interfaces needing standard frequency references

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 rail is stable within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and a compact 2.0x1.6mm footprint is required. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the standby feature if power efficiency is a critical constraint in the application environment compared to continuous oscillation alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series typically offers various standard frequencies in a consistent small outline package. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from non-stby variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 26.736 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functions to ensure electrical equivalence.
