18QHTF21-27.064-OE

Oscillators Overview

The 18QHTF21-27.064-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.064 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• General purpose digital circuit timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent operational damage during integration.

Oscillators Selection Notes

Select this component when a precise 27.064 MHz reference is required for LVCMOS-compatible digital systems. The choice is driven by the need for low-voltage operation at 1.8V and the space-saving benefits of the small 2.0x1.6mm SMD package. Consider the enable pin utility if dynamic power saving is a design priority over continuous oscillation.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within the same physical footprint and electrical profile. The 'OE' suffix typically denotes specific packaging or tape-and-reel configuration details as defined by the manufacturer's ordering nomenclature.

Oscillators Replacement Considerations

Direct substitutes must match the 27.064 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications before substituting with components from other manufacturers.
