QTM216J-8.192MDJ-T

Overview

The QTM216J-8.192MDJ-T is a standard CMOS crystal oscillator manufactured by QST, designed for surface-mount applications. It operates at a fixed frequency of 8.192 MHz with a supply voltage of 1.8V. The device features an enable/disable function and exhibits a frequency stability of ±50ppm across the operating temperature range of -40°C to +105°C. Maximum supply current is 22mA. The component is housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm.

Feature Summary

• Integrated enable and disable functionality for power management control
• CMOS output interface compatible with low-voltage digital logic
• Compact 4-SMD surface-mount package design for space-constrained layouts

Applications

• Embedded system clock generation
• Portable electronic devices requiring low-power operation
• Industrial control modules

Procurement Notes

Verify the complete part number including suffixes such as 'T' for tape-and-reel packaging against official distributor catalogs. Confirm that the 1.8V supply requirement aligns with target circuit designs. Ensure compatibility with the specified -40°C to +105°C industrial temperature range before procurement. Cross-reference manufacturer datasheets for pinout and electrical characteristics.

Selection Notes

Select this component when a precise 8.192 MHz reference is required in ultra-small form factors. The 1.8V supply voltage suits modern low-power digital systems. Consider the ±50ppm stability specification for timing accuracy requirements. The enable/disable feature allows for dynamic power savings in battery-operated applications compared to always-on oscillators.

Part Context

This model belongs to the QTM216J series of quartz crystal oscillators from QST. The series utilizes ceramic or quartz resonator technology to provide stable clock signals. The 2.0x1.6mm footprint represents one of the smallest packages in the lineup, targeting high-density PCB designs where space is limited.

Replacement Considerations

Check for direct substitutes like QTM216J-8.192MBJ-T if different voltage or packaging options are needed. Verify pin compatibility and electrical specifications before swapping components. Consult manufacturer cross-reference guides for validated alternatives.
