18QHTF21-2.94912-OE

Oscillators Overview

The 18QHTF21-2.94912-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.94912 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports enable/disable functionality for power optimization
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed as a quartz-based standard crystal oscillator

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-power digital circuits
• Consumer electronics requiring precise frequency standards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Ensure the 1.8V supply voltage aligns with the target system's power rails. Confirm that the enable/disable pin logic levels are compatible with the controlling microcontroller or GPIO to prevent unintended oscillation states.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 2.94912 MHz frequency. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Consider the enable/disable feature if power efficiency during idle periods is a critical design parameter compared to always-on alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which offers various frequencies within the same form factor. The series typically includes options ranging from low MHz frequencies up to higher speeds, all sharing similar electrical characteristics and package dimensions to facilitate design reuse across different product lines.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical footprints but different frequencies, such as 18QHTF21-3.57952-OE, provided the frequency difference is acceptable. Cross-brand replacements must match the 2.0x1.6mm SMD package, 1.8V supply, and LVCMOS output type.
