18QHTF21-117.000-OE

Overview

The 18QHTF21-117.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 117 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, no lead package suitable for surface mount applications. The component supports an operating temperature range of -40°C to 85°C with a frequency stability of ±50ppm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Enable/disable functionality for power management
• Compact 4-SMD no lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

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 PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet. Check for any specific handling instructions related to the surface mount technology used in this component series.

Selection Notes

Select this oscillator when a precise 117 MHz clock signal is required for LVCMOS-compatible digital circuits. Consider the ±50ppm stability specification for applications sensitive to timing jitter. The enable/disable feature makes it suitable for battery-powered devices requiring power optimization. Evaluate the thermal performance within the -40°C to 85°C range to ensure reliability under varying environmental conditions.

Part Context

This component belongs to the 18QHTF21 series of surface mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, including 3.3V variants. The 'OE' suffix typically denotes specific packaging or tape-and-reel configurations. Mercury Electronics is a established manufacturer of frequency control products with a history dating back to 1973.

Replacement Considerations

Direct replacements must match the 117 MHz frequency, LVCMOS output, and 1.8V supply voltage. Compatible alternatives include other models from the same series such as 18QHTF21-117.675-OE if frequency flexibility exists. Verify pinout compatibility and package dimensions to ensure mechanical fit without redesigning the PCB layout.
