The component includes enable/disable functionality and is supplied in reels of 3000 units.

Feature Summary

• Compact surface-mount design suitable for space-constrained applications
• Low jitter and phase noise performance characteristics
• Integrated enable and disable control functionality

Applications

• General purpose digital clock signal generation
• Embedded systems requiring precise timing references
• Communication equipment utilizing standard CMOS interfaces

Procurement Notes

Verify the manufacturer designation carefully, as this part number is associated with TXC Corporation despite the requested brand query. Confirm the specific suffix 'MDJ' corresponds to the 1.8V supply and ±50ppm stability requirements. Ensure the order quantity aligns with the standard reel packaging configuration provided by the supplier. Cross-reference the datasheet for pinout compatibility before integration.

Selection Notes

Select this component when a low-profile 2.5x2.0mm footprint is required for 1.8V CMOS clocking applications. The wide industrial temperature range supports operation in demanding environments. Consider the enable/disable feature if power management or clock gating is necessary within the system architecture. Verify that the load capacitance requirements match the target circuit design specifications.

Part Context

This oscillator belongs to the QTM252J series, which offers various frequency options within the same physical package. The series provides standardized timing solutions for consumer electronics and industrial controls. Competing products typically offer similar form factors but may differ in electrical specifications or supply voltage ranges. The model represents a specific frequency variant within this broader family of quartz ceramic oscillators.

Replacement Considerations

Direct substitutes include other models from the QTM252J series with different frequencies, such as QTM252J-1.8432MDE-T, though supply voltage variations must be checked. Generic replacements require matching the 4-SMD package, 1.8V operation, and CMOS output type. Always verify frequency stability and temperature range compliance when substituting.
