18QHTF21-3.136-OE

Oscillators Overview

The 18QHTF21-3.136-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 3.136 MHz and utilizes LVCMOS output logic. The device supports 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.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Standard frequency operation at 3.136 MHz
• Compact 4-SMD no lead surface mount package

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 target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the enable pin logic levels are compatible with the controlling microcontroller or GPIO to prevent unintended oscillation states during operation.

Oscillators Selection Notes

Select this component when a fixed 3.136 MHz timing source is required with minimal footprint constraints. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the enable feature if power management or clock gating is necessary within the application architecture.

Oscillators Part Context

This part belongs to Mercury's QuikXO series, which focuses on fast-delivery CMOS output clock oscillators. The series includes both standard and custom frequency options built to order. Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in quartz crystals and timing components since 1973.

Oscillators Replacement Considerations
