18QHTF21-11.700-OE

Overview

The 18QHTF21-11.700-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 11.7 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for surface-mount assembly and is suitable for applications requiring precise timing signals within consumer and industrial electronic systems.

Feature Summary

• Integrates LVCMOS output logic for direct interface with digital circuits
• Features built-in enable/disable functionality for efficient power control
• Utilizes a compact 4-SMD no-lead surface mount package design

Applications

• Consumer electronics timing circuits
• Industrial control system synchronization
• General-purpose clock signal generation

Procurement Notes

Verify the specific suffix (OE) against the manufacturer's current documentation to confirm exact electrical tolerances and pinout configurations. Ensure that the 1.8V supply requirement aligns with the target system's power rails. Confirm package compatibility during PCB layout review to avoid soldering defects associated with small form factor components.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 11.7 MHz frequency. The LVCMOS output is appropriate for general digital logic interfacing without additional level shifting. Consider the enable feature if dynamic power saving is necessary. Verify temperature range specifications against the operational environment requirements before finalizing the design.

Part Context

This part belongs to the Mercury QHTF series of quartz crystal oscillators. The series typically offers various frequency options within a standardized small footprint. Mercury Electronics specializes in frequency control products, including crystals and oscillators, serving both consumer and industrial markets with reliable timing solutions.

Replacement Considerations

Check for parts with identical 11.7 MHz frequency, 1.8V supply, and LVCMOS output. Ensure the replacement maintains the 4-SMD 2.0x1.6mm package dimensions and enable/disable functionality for direct board compatibility.
