18QHTF21-26.63716-PD

Oscillators Overview

The 18QHTF21-26.63716-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 26.63716 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features a standby power-down function and is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for energy efficiency
• Includes standby mode to reduce power consumption when inactive
• Utilizes LVCMOS output logic for digital circuit compatibility

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations required by your application environment.

Oscillators Selection Notes

Select this component when a precise 26.63716 MHz timing source is required in space-constrained designs. The 1.8V supply makes it suitable for modern low-power digital applications. Consider the LVCMOS output level compatibility with your receiving logic gates. The small form factor allows for high-density board layouts where larger packages are not feasible.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 2.0x1.6mm SMD package. The series is designed for applications requiring stable clock signals with minimal power consumption. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable frequency control products.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with different frequencies but identical pinouts and electrical characteristics, such as 18QHTF21-25.000-PD or 18QHTF21-27.000-PD, provided the frequency difference is acceptable for the application.
