18QHTF21-10.667-OE

Overview

The 18QHTF21-10.667-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 10.667 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports Enable/Disable functionality for power management
• Utilizes LVCMOS output logic for digital interfacing
• Designed as a standard XO (Crystal Oscillator)

Applications

• General clock signal generation
• Digital circuit timing reference

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the 1.8V supply voltage aligns with your target platform's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints to avoid assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. Consider the small 2.0x1.6mm form factor for space-constrained designs. Verify compatibility with LVCMOS logic levels in the receiving circuitry to ensure proper signal integrity and noise margins during operation.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The manufacturer specializes in quartz crystals and oscillators, offering products like TCXOs and VCTCXOs. This specific model represents a standard fixed-frequency solution within their portfolio.

Replacement Considerations

Direct substitutes include other 10.667 MHz LVCMOS oscillators in similar SMD packages from different manufacturers. Ensure equivalent electrical specifications such as supply voltage and output logic are matched. Cross-reference pinouts and thermal characteristics if replacing with components from alternative suppliers.
