18QHTF21-26.800-PD

Oscillators Overview

The 18QHTF21-26.800-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 26.8 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a maximum supply current of 23 mA. It includes a standby function for power-down control. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 mm by 1.6 mm.

Oscillators Feature Summary

• Generates a precise 26.8 MHz clock signal using LVCMOS logic levels
• Operates on a single 1.8V power supply with low current consumption
• Supports standby mode to reduce power usage during inactive periods
• Utilizes a small footprint surface-mount package for space-constrained designs

Oscillators Applications

• Clock generation for digital signal processors
• Timing reference for microcontroller units
• Synchronization in communication interfaces
• Power management systems requiring low-voltage timing sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable within the operational limits. Ensure the PCB layout accommodates the 2.0x1.6mm SMD package dimensions. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Oscillators Selection Notes

Select this component when a 26.8 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage for compatibility with modern low-voltage logic families. Evaluate the need for a standby feature to manage power efficiency in battery-operated devices. Compare the physical size constraints against alternative packages if space is limited.
