18QHTF21-49.360-OE

Overview

The 18QHTF21-49.360-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 49.36 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount assembly.

Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated enable and disable control pin
• Surface-mount 4-pin no-lead package design

Applications

• High-performance digital systems requiring precise timing
• Embedded controllers utilizing LVCMOS logic levels
• Portable electronics with 1.8V power domains

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics to validate electrical characteristics for your specific application environment.

Selection Notes

Select this component when a 49.36 MHz clock signal is required with LVCMOS compatibility. The 1.8V operating voltage makes it suitable for low-power applications. Consider the enable/disable feature if power conservation during idle states is necessary. Verify that the physical dimensions of the 4-SMD package fit within the available board space.

Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series typically offers standard frequency options with LVCMOS outputs. These components are designed for general-purpose timing applications where size and power consumption are critical factors. The -OE suffix may indicate specific packaging or testing variations defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the 49.36 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD package. Check equivalent parts from other manufacturers offering similar timing specifications and form factors.
