18QHTF21-109.620-OE

Overview

The 18QHTF21-109.620-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 109.62 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes enable/disable functionality 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 applications and typically exhibits a frequency stability of ±50ppm over the operating temperature range of -40°C to +85°C.

Feature Summary

• Compact 2.0x1.6 mm surface-mount package design
• LVCMOS output logic compatible with low-voltage systems
• Integrated enable and disable control functionality
• Standard XO configuration for precise clock generation

Applications

• High-speed data communication interfaces
• Embedded system clock sources
• Consumer electronics timing circuits
• Industrial control board synchronization

Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm exact electrical characteristics and pinout compatibility. Ensure that the 1.8V supply requirement aligns with your target circuit design before procurement. Cross-reference the package dimensions with your PCB footprint library to guarantee accurate mechanical fit during assembly processes.

Selection Notes

Select this component when a low-profile, high-frequency clock source is required for space-constrained designs. The 1.8V operation makes it suitable for modern low-power digital logic families. Consider the ±50ppm stability specification relative to your system's jitter tolerance requirements. Evaluate the enable/disable feature if dynamic power saving is necessary for the application lifecycle.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz frequency control products. The manufacturer has decades of experience in producing crystals, oscillators, and filters. This series represents their standard XO offerings, balancing performance with compact form factors for widespread electronic integration needs.

Replacement Considerations

Direct substitutes may include other 109.62 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers. Verify equivalent supply voltage, current consumption, and stability specifications. Ensure pin-to-pin compatibility if replacing on existing PCB layouts without redesigning the footprint.
