QTM252J-16.000MBJ-T

Overview

The QTM252J-16.000MBJ-T is a standard CMOS quartz oscillator manufactured by TXC Corporation under the QST brand. It operates at a frequency of 16 MHz with a supply voltage of 3.3 V and a frequency stability of ±50 ppm. The device features an enable/disable function and is housed in a 4-SMD, no-lead package measuring 2.5 mm x 2.0 mm. It supports an operating temperature range of -40°C to +105°C.

Feature Summary

• Compact 2.5x2.0 mm surface-mount ceramic package for space-constrained designs
• Integrated enable/disable control pin for power management
• CMOS output signal compatible with digital logic interfaces

Applications

• General-purpose clock generation for embedded systems
• Consumer electronics requiring small form factor oscillators
• Industrial equipment operating within extended temperature ranges

Procurement Notes

Verify the manufacturer designation, as the component is produced by TXC Corporation while marketed under the QST brand identifier. Confirm the specific suffix 'MBJ' corresponds to the 3.3V supply voltage and enable/disable functionality. Ensure the order quantity aligns with the standard factory packaging requirement of 3000 units per reel. Cross-reference the datasheet for precise pinout and electrical characteristics before integration.

Selection Notes

Select this model when a 16 MHz clock source is required with a 3.3V logic interface. The ±50 ppm stability suits general applications where high precision is not critical. The enable/disable feature allows for dynamic power control. Consider the 2.5x2.0 mm footprint against available PCB real estate. Verify thermal requirements against the -40°C to +105°C operational range.

Part Context

This component belongs to the QTM252J series of low jitter CMOS quartz oscillators. The series offers various frequencies and voltage options within a standardized 2520 package. It serves as a timing reference for microcontrollers, memory interfaces, and communication ports. The QST branding indicates distribution or specific product line alignment by TXC Corporation.

Replacement Considerations

Direct substitutes include other 16 MHz CMOS oscillators in 2520 packages with 3.3V operation and enable pins. Verify compatibility regarding pin configuration, output waveform, and load capacitance. Alternative part numbers from different manufacturers may require schematic adjustments if pinouts differ.
