18QHTF21-49.3767-OE

Oscillators Overview

The 18QHTF21-49.3767-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 49.3767 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function. 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 functions within a specified operating temperature range.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control functionality
• Utilizes a small form factor SMD package for space-constrained designs

Oscillators Applications

• General purpose timing clock generation
• Digital signal processing systems
• Communication equipment interfaces

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the exact pinout and electrical characteristics. Ensure the 1.8V supply requirement aligns with the target system design. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check for any specific handling requirements associated with the no-lead SMD package type during assembly.

Oscillators Selection Notes

Select this component when a precise 49.3767 MHz reference is required in low-profile applications. The 1.8V operation makes it suitable for modern low-power digital circuits. Consider the enable/disable feature if power management or clock gating is necessary. Verify that the 2.0x1.6mm footprint fits within the available PCB area constraints compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The manufacturer specializes in quartz crystals and timing components. The 18QHTF21 series indicates a specific family of surface-mount devices. This model represents a fixed-frequency variant within their broader portfolio of timing solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 49.3767 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify equivalent performance specifications from other manufacturers before substitution.
