18QHTF21-116.5441-OE

Overview

The 18QHTF21-116.5441-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 116.5441 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features an enable/disable control capability for power management efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed to provide stable timing signals for precision electronic applications requiring low-profile surface-mount integration.

Feature Summary

• Provides precise frequency generation at 116.5441 MHz using standard XO technology
• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes hardware enable and disable functionality for dynamic power control
• Utilizes a small-footprint 4-SMD no-lead package for space-constrained designs

Applications

• Precision timing circuits in consumer electronics
• Data communication interfaces requiring stable clock sources
• Embedded systems with limited board space
• Portable devices utilizing low-voltage logic families

Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm pinout and electrical characteristics match your design requirements. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Cross-reference the 4-SMD package dimensions with your PCB footprint library to guarantee mechanical fit during assembly.

Selection Notes

Select this component when a fixed frequency of 116.5441 MHz is required with minimal board area consumption. The 1.8V supply requirement makes it suitable for modern low-power digital systems. The enable/disable feature offers flexibility for power-sensitive applications where the oscillator can be deactivated when not in use. Consider the LVCMOS output type for direct interfacing with standard CMOS-based processors or FPGAs without additional level shifting.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series is characterized by its small form factor and low voltage operation. Mercury Electronics has been a manufacturer of frequency control products since 1973, specializing in quartz crystals and oscillators. The 18QHTF21 series represents their standard XO offerings designed for high-volume consumer and industrial applications.

Replacement Considerations

Direct substitutes include other 116.5441 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers such as Epson or NDK. Verify that any replacement maintains the same 1.8V supply voltage and enable/disable pin configuration. Ensure the load capacitance and drive strength specifications are compatible with the target circuit to maintain signal integrity.
