18QHTF21-10.762238-OE

Overview

The 18QHTF21-10.762238-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.762238 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. 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 management
• 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 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 specified in the official datasheet to guarantee proper solder joint formation and mechanical stability during operation.

Selection Notes

Select this component when a precise 10.762238 MHz reference is required for LVCMOS-compatible digital circuits. The choice depends on the necessity for an enable/disable pin to optimize standby power states. Consider the physical size constraints of the 4-SMD package relative to available board space. Evaluate the operating temperature range specifications to ensure reliability under expected environmental conditions.

Part Context

This oscillator belongs to the Mercury Electronics standard XO series, which provides reliable frequency control solutions. The brand has extensive experience in quartz crystal manufacturing since 1973. This specific model represents a standard configuration within their portfolio, offering a balance between performance and cost-effectiveness for common timing applications in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 10.762238 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent electrical parameters such as phase noise and jitter if critical. Check for identical pinout configurations to ensure compatibility without redesigning the footprint.
