18QHTF21-83.300-OE

Overview

The 18QHTF21-83.300-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 83.3 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise clock signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated Enable/Disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring 1.8V operation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target circuit design. Confirm the 4-SMD package dimensions fit the PCB footprint constraints. Cross-reference the OE suffix to ensure the enable/disable feature is required for the application.

Selection Notes

Select this component when a stable 83.3 MHz clock source is needed with low voltage operation. The LVCMOS output is appropriate for standard digital logic families. Consider the Enable/Disable pin if power management or clock gating is part of the system architecture. Verify temperature range specifications match the operational environment.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series supports different supply voltages and output types. The 18QHTF21-83.300-OE specifically targets the 83.3 MHz frequency point with 1.8V operation and enable control, distinguishing it from other variants in the lineup.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical frequency and package, such as 18QHTF21-83.300-PD if pinout and electrical characteristics are compatible. Always verify that the replacement maintains the LVCMOS output type and 1.8V supply requirement.
