QTM216J-24.576MDJ-T

Overview

The QTM216J-24.576MDJ-T is a surface-mount CMOS oscillator manufactured by QST, designed for compact electronic applications. It operates at a nominal frequency of 24.576 MHz with a frequency stability of ±50 ppm. The device supports a supply voltage of 1.8V and features an enable/disable function via the OE pin. It utilizes a 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. The component is rated for an operating temperature range of -40°C to +105°C.

Feature Summary

• Compact 2.0x1.6mm SMD footprint suitable for space-constrained designs
• CMOS output with enable/disable control functionality
• Wide industrial operating temperature range from -40°C to +105°C

Applications

• Wireless communication modules requiring precise clock sources
• Portable consumer electronics with limited board space
• Industrial control systems operating in varying temperatures

Procurement Notes

Verify the specific suffix 'MDJ-T' against the manufacturer's datasheet to confirm the exact voltage (1.8V) and temperature grade (-40°C to +105°C). Ensure the ordering part number matches the required frequency tolerance and package type. Cross-reference with authorized distributors to confirm availability and authenticity of the QST component.

Selection Notes

Select this model when a low-profile 2.0x1.6mm oscillator is required for 1.8V logic interfaces. The ±50 ppm stability is suitable for general-purpose timing applications. Consider the enable/disable feature for power management requirements. Verify that the 15pF load capacitance matches the target circuit design before finalizing the selection.

Part Context

This component belongs to the QTM216 series of low EMI CMOS oscillators from QST. The series offers various frequencies and voltage options within the same small form factor. The J suffix typically denotes specific temperature or stability grades within the product line, distinguishing it from other variants like the QTM216E series.

Replacement Considerations

Direct substitutes must match the 2.0x1.6mm package, 1.8V supply, and 24.576MHz frequency. Check compatibility of the enable pin logic levels and output drive strength. Verify that alternative components meet the -40°C to +105°C operating temperature range and ±50 ppm stability requirement.
