18QHTF21-4.630-OE

Oscillators Overview

The 18QHTF21-4.630-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 4.63 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package. The component supports an operating temperature range from -40°C to 85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• Supports enable and disable control functions for power management
• Utilizes LVCMOS output logic interface
• Designed for operation within industrial temperature ranges

Oscillators Applications

• General purpose timing circuits requiring low voltage operation
• Embedded systems with space-constrained layouts
• Industrial equipment operating in variable thermal environments

Oscillators Procurement Notes

Verify the specific suffix 'OE' corresponds to the Enable/Disable functionality rather than Power Down variants like 'PD'. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Ensure the 4-SMD no-lead package footprint matches the PCB design constraints. Cross-reference the ±50ppm stability specification against the application's timing tolerance requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and precise enable/disable control is required. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the ±50ppm stability limit for applications not requiring high-precision clocking. The wide temperature range makes it appropriate for industrial or automotive-grade deployments where environmental extremes are expected.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has extensive experience in Taiwan's crystal industry. This specific model represents a standard XO variant designed for modern electronic devices requiring small form factors and reliable timing signals under varying load conditions.

Oscillators Replacement Considerations

The 18QHTF21-4.630-PD is a related variant offering standby power-down functionality instead of simple enable/disable. Verify if the control logic difference impacts the system design. Other frequencies in the same package family may serve as alternatives if the 4.63 MHz requirement is flexible.
