18QHTF21-47.032-OE

Oscillators Overview

The 18QHTF21-47.032-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 47.032 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• General purpose clock signal generation
• Digital system timing reference
• Embedded controller clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the enable/disable pin configuration matches the system's power management strategy to avoid unintended operation states during standby modes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The enable/disable feature makes it suitable for power-sensitive designs where clock gating is necessary. Consider the small footprint of the 4-SMD package for space-constrained PCB layouts compared to larger through-hole or standard SMD oscillators.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHT series of surface-mount crystal oscillators. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes specific packaging or tape-and-reel specifications common in their distribution channels. It represents a standard fixed-frequency solution within their broader portfolio of quartz-based timing devices.

Oscillators Replacement Considerations

Direct replacements must match the 47.032 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify if the substitute supports the same enable/disable control logic. Cross-reference pinouts to ensure compatibility without circuit modification.
