18QHTF21-116.444-OE

Overview

The 18QHTF21-116.444-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 116.444 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This surface-mount oscillator is suitable for high-density circuit designs requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• High-speed data communication interfaces
• Digital signal processing systems
• Network equipment timing circuits

Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current product catalog to ensure availability and confirm that the enable/disable feature is active as specified. Cross-reference the 1.8V supply requirement with the target system's power rails to guarantee electrical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a 116.444 MHz clock source is required with low voltage operation. Ensure the design supports the 1.8V logic level and accommodates the 2.0x1.6mm footprint. Consider the enable/disable pin requirement if power management during idle states is necessary for the application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or operational characteristics defined by the manufacturer, distinguishing it from other variants in the same physical form factor family.

Replacement Considerations

Direct substitutes include the 18QHTF21-116.444-PD variant, which shares the same frequency and package but may differ in operational parameters. Verify electrical specifications and pinout compatibility before swapping components to ensure circuit integrity.
