18QHTF21-42.3724-OE

Oscillators Overview

The 18QHTF21-42.3724-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 42.3724 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• Digital clock signal generation
• Microcontroller system timing
• Communication interface synchronization

Oscillators 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 to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable pin feature makes it suitable for battery-powered or power-sensitive designs. Consider the 42.3724 MHz frequency specifically for applications requiring this exact clock rate rather than standard frequencies like 40MHz or 50MHz.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which focuses on quartz-based frequency control products. The manufacturer specializes in oscillators, crystals, and filters. This specific model represents a standard non-spread spectrum oscillator variant within their portfolio of surface-mount timing devices.

Oscillators Replacement Considerations

Direct substitutes must match the 42.3724 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before cross-referencing other manufacturers' offerings.
