18QHTF21-27.29964-OE

Oscillators Overview

The 18QHTF21-27.29964-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 27.29964 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

• Integrates LVCMOS output logic for digital signal interfacing
• Supports active enable and disable control states
• Utilizes a surface-mount 4-pin no-lead package design

Oscillators Applications

• Embedded clock generation systems
• Digital signal processing interfaces
• Communication module timing sources

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as OE variants may differ from PD or other suffixes regarding strip or tape-and-reel delivery. Confirm that the 1.8V supply requirement aligns with the target system power rails before integration. Ensure the 2.0x1.6mm footprint matches the PCB land pattern specifications to prevent assembly defects.

Oscillators Selection Notes

Select this component when a precise 27.29964 MHz reference is required for low-voltage digital circuits. The 1.8V operating voltage makes it suitable for modern portable and battery-powered devices. Consider the enable/disable functionality if power management during idle states is a critical design requirement.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The manufacturer is a specialized producer of frequency control products with a history dating back to 1973.

Oscillators Replacement Considerations

Direct substitutes include other 27.29964 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and envelope dimensions against alternatives such as similar Mercury models or competitors offering identical electrical parameters.
