18QHTF21-43.04895-OE

Oscillators Overview

The 18QHTF21-43.04895-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 43.04895 MHz and utilizes LVCMOS output logic. The device requires 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.

Oscillators Feature Summary

• Supports active low enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed in a small form factor surface-mount package

Oscillators Applications

• Embedded systems requiring precise clock timing
• Consumer electronics with space constraints
• Industrial control modules

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The enable pin allows for system-level power saving strategies. Consider the physical size constraints of the application, as the 2.0x1.6mm package is suitable for dense board layouts where larger oscillators cannot fit.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The manufacturer specializes in quartz crystals and frequency control products, including TCXOs and VCXOs. This specific model represents a standard fixed-frequency option within their portfolio of surface-mount oscillators.

Oscillators Replacement Considerations

Direct substitutes must match the 43.04895 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in competitor datasheets.
