18QHTF21-3.763-OE

Oscillators Overview

The 18QHTF21-3.763-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fundamental frequency of 3.763 MHz and utilizes LVCMOS output logic levels. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount assembly. The unit supports an operating temperature range of -40°C to 85°C with a frequency stability of ±50ppm.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Active enable/disable control pin for power optimization
• Compact 4-pin SMD no-lead surface mount package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Consumer electronics requiring low-power oscillators
• Industrial control systems operating within extended temperature ranges

Oscillators Procurement Notes

Verify the specific frequency suffix (3.763) matches the design requirement. Confirm the 1.8V supply voltage aligns with the target circuit. Ensure the LVCMOS output type is compatible with the receiving logic inputs. Check the 4-SMD package dimensions against the PCB footprint. Validate the ±50ppm stability meets system timing tolerances.

Oscillators Selection Notes

Select this component when a precise 3.763 MHz reference is required for low-voltage digital circuits. The enable feature makes it suitable for battery-operated applications where power conservation is critical. Consider the ±50ppm stability for general-purpose timing rather than high-precision synchronization. The wide temperature range supports diverse environmental conditions.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products, including quartz crystals and oscillators. The company has decades of experience in producing timing components for various industries. This model belongs to their standard XO series, designed for cost-effective and reliable clock generation solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 3.763 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify that any alternative component offers equivalent ±50ppm stability and the same enable/disable functionality. Ensure thermal ratings cover the -40°C to 85°C range.
