QTM216J-25.000MDJ-T

Overview

The QTM216J-25.000MDJ-T is a surface-mount CMOS oscillator manufactured by QST, operating at a frequency of 25 MHz. It functions as a standard XO with an enable/disable control feature and requires a 1.8V supply voltage. The device utilizes a 4-SMD, no-lead package with dimensions of 2mm x 1.6mm. It maintains a frequency stability of 50ppm and supports an output load of 15 pF. This component is designed for compact electronic applications requiring precise timing signals.

Feature Summary

• Surface mount CMOS technology
• Enable/Disable functionality
• Compact 4-SMD package

Applications

• Embedded systems
• Communication modules
• Memory interfaces

Procurement Notes

Verify the specific suffix MDJ-T to ensure compatibility with the required 25MHz frequency and 1.8V operation. Confirm that the 4-SMD no-lead footprint matches the target PCB design. Ensure the 50ppm stability meets system timing requirements. Check RoHS compliance status if restricted substances are a concern for the final assembly.

Selection Notes

Select this component when a low-profile 2mm x 1.6mm oscillator is required for 1.8V logic circuits. The CMOS output type suits digital interfaces directly. The enable/disable pin allows for power management strategies in battery-operated devices. Consider the 50ppm tolerance against the system's clock accuracy needs.

Part Context

This part belongs to the QTM216J series of surface-mount oscillators from QST. The series offers various frequencies and supply voltages within the same compact form factor. The QTM216J model specifically targets applications needing reliable timing in space-constrained designs.

Replacement Considerations

Direct substitutes must match the 25MHz frequency, 1.8V supply, CMOS output, and 4-SMD 2x1.6mm package. Verify pinout compatibility for the OE/Disable function before substitution.
