18QHTF21-111.992-OE

Overview

The 18QHTF21-111.992-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 111.992 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

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

Applications

• Digital signal processing systems requiring precise clock timing
• Communication equipment utilizing high-frequency oscillators
• Embedded systems needing low-voltage clock sources

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure compatibility with required enable/disable pin configurations. Confirm that the 1.8V supply voltage aligns with the target system's power rails before integration. Check package dimensions for PCB footprint accuracy.

Selection Notes

Select this component when a 111.992 MHz clock signal is required with LVCMOS compatibility. Ensure the design supports the 1.8V operating voltage and includes circuitry for the enable/disable control feature. Consider the small form factor for space-constrained layouts.

Part Context

This part belongs to the Mercury Electronics XO series, designed for general-purpose clock generation. The 18QHTF21 series typically offers standard performance levels suitable for consumer and industrial electronics. Mercury Electronics specializes in quartz crystal and oscillator manufacturing.

Replacement Considerations

Direct substitutes must match the 111.992 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, especially regarding the enable/disable control line, before swapping components.
