18QHTF21-11.0044-OE

Overview

The 18QHTF21-11.044-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 11.044 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features an enable/disable pin for power management control
• Utilizes a surface-mount 4-SMD no-lead package design

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for embedded systems
• Digital communication interfaces requiring stable frequency

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure correct frequency and package specifications. Confirm that the 1.8V supply voltage requirement aligns with the target system design before procurement. Check for availability status as components may be subject to discontinuation or supply chain variations.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 11.044 MHz frequency. Ensure the application supports LVCMOS logic levels and requires an enable/disable feature for power optimization. Verify that the 2.0x1.6mm footprint fits within the PCB layout constraints.

Part Context

This oscillator belongs to the Mercury Electronics XO series, which specializes in quartz-based frequency control products. The manufacturer has extensive experience in producing crystals and oscillators, positioning itself as a pioneer in the Taiwan quartz industry since 1973.

Replacement Considerations

Direct substitutes include other 11.044 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as load capacitance and drive level before substitution.
