QTM325-33.333MBE-T

Overview

The QTM325-33.333MBE-T is a standard clock oscillator manufactured by QST Products LLC, operating at a nominal frequency of 33.333 MHz with a CMOS output signal. It features a frequency stability of ±50 ppm and operates within a temperature range of -40°C to +85°C. The device is powered by a single 3.3V DC supply voltage and utilizes a ceramic quartz construction. It is housed in a surface-mount package measuring 3.2mm x 2.5mm x 1.0mm with four pins.

Feature Summary

• CMOS output signal generation for digital logic compatibility
• Quartz crystal resonator construction for precise timing
• Surface-mount design optimized for automated assembly

Applications

• Standard clock signal distribution in electronic systems
• Timing reference for microprocessors and FPGAs
• Synchronization source for communication interfaces

Procurement Notes

Verify the manufacturer designation on official documentation, as some sources list TXC Corporation while others specify QST Products LLC. Confirm the specific package dimensions and pin configuration against the latest datasheet before integration. Ensure the supply voltage requirement matches the system design constraints.

Selection Notes

Select this component when a 33.333 MHz clock source with ±50 ppm stability is required. The 3.3V operating voltage must align with the target circuit's power rails. Consider the 3.2x2.5mm footprint for PCB layout compatibility. Verify the CMOS output type suits the receiving input logic levels.

Part Context

This part belongs to the QTM325 series of standard clock oscillators. Similar models in the series include variants with different frequencies such as 32.000 MHz or 50.000 MHz, sharing the same SMD3225-4P package and electrical characteristics. The series provides reliable timing solutions for compact electronic designs.

Replacement Considerations

Direct substitutes may include other 33.333 MHz CMOS oscillators in the SMD3225-4P package from manufacturers like TXC Corporation, provided electrical parameters match. Cross-reference pinouts and voltage requirements carefully.
