18QHTF21-2.1888-OE

Oscillators Overview

The 18QHTF21-2.1888-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 2.1888 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package, suitable for surface-mount assembly.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated enable/disable control pin
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing clock sources
• Microcontroller system timing
• Embedded communication interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a precise 2.1888 MHz reference is required for low-power applications. The LVCMOS output is compatible with standard digital logic families operating at 1.8V. Consider the enable feature if dynamic power saving is necessary for battery-operated devices or systems requiring clock gating capabilities.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronic. The series offers various frequencies within the SMD form factor. The suffix OE typically denotes specific packaging or tape-and-reel configuration details as defined by the manufacturer's ordering nomenclature.

Oscillators Replacement Considerations

Direct replacements must match the 2.1888 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD package outline. Verify pin compatibility and electrical characteristics with other manufacturers' equivalent parts before substitution.
