18QHTF21-48.461-OE

Overview

The 18QHTF21-48.461-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 48.461 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications, specifically requiring a 1.8V supply voltage. It features an enable/disable control function to manage power consumption effectively. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly. This oscillator is part of the company's lineup aimed at reducing overall system power usage while maintaining precise timing signals.

Feature Summary

• Low voltage CMOS design for reduced power consumption
• Integrated enable and disable functionality
• Standard LVCMOS output logic compatibility

Applications

• General purpose clock signal generation
• Digital circuit timing synchronization
• Embedded systems requiring low power operation

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm exact electrical tolerances and pinout configurations. Ensure that the 1.8V supply requirement aligns with your target board design. Cross-reference the 4-SMD no-lead package dimensions with your PCB footprint library to guarantee mechanical fit. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a 48.461 MHz reference clock is required with minimal power draw. The LVCMOS interface ensures compatibility with standard digital logic families operating at 1.8V. Consider the enable/disable feature if dynamic power management is necessary for the application. The small form factor makes it suitable for space-constrained designs where traditional packages cannot be accommodated.

Part Context

Mercury Electronic Ind. Co., Ltd. specializes in frequency control products including quartz crystals and oscillators.
