18QHTF21-16.9344-OE

Oscillators Overview

The 18QHTF21-16.9344-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 16.9344 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and features an Enable/Disable control interface for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Provides stable 16.9344 MHz clock signal generation using LVCMOS output standards
• Operates on a single 1.8V power supply rail
• Includes hardware control capability via dedicated Enable/Disable pin functionality

Oscillators Applications

• Digital system clock distribution
• Microprocessor timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronic documentation to confirm the Enable/Disable function versus other variants like 'PD'. Ensure the 1.8V operating voltage aligns with target circuit design requirements. Confirm the 4-SMD No Lead package dimensions match PCB footprint specifications before integration.

Oscillators Selection Notes

Select this component when a 16.9344 MHz frequency is required alongside low-voltage 1.8V operation. The Enable/Disable feature distinguishes it from standard continuous-output oscillators. Consider the small form factor for space-constrained designs. Validate that LVCMOS output swing meets downstream input threshold requirements.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. specializes in frequency control products including quartz crystals and oscillators. This model belongs to their XO series, designed for general-purpose timing applications. The company has established manufacturing capabilities in Taiwan for decades, focusing on precision frequency stability.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-16.9344-PD, which shares the same frequency and package but uses Standby/Power Down control instead of Enable/Disable. Verify functional equivalence regarding control logic polarity and electrical characteristics before substitution.
