18QHTF21-75.957292-OE

Overview

The 18QHTF21-75.957292-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 75.957292 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. Key functional features include an enable/disable control pin for power management. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power optimization
• Compact 4-SMD no-lead surface mount package design

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Procurement Notes

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

Selection Notes

Select this component when a precise 75.957292 MHz clock source is required with low voltage operation. Consider the LVCMOS output swing limits relative to the receiving logic family. Evaluate the enable pin utility if dynamic power saving is necessary. Compare package size constraints against available board space for the 4-SMD form factor.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount oscillators. The series typically offers various frequencies within the same physical footprint. The 'OE' suffix likely denotes a specific ordering or packaging variant, though functional differences are not explicitly defined in public summaries. It serves as a direct replacement for other 75.957292 MHz oscillators in compatible designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications carefully when considering alternative manufacturers. Ensure the replacement supports the same 1.8V supply and LVCMOS output characteristics.
