TSM75-H50CQ33ST-125.000M-TR

Oscillators Overview

The TSM75-H50CQ33ST-125.000M-TR is a standard crystal oscillator (XO) from the TSM75 series manufactured by Transko Electronics, Inc. It operates at a fixed frequency of 125.000 MHz with HCMOS output logic levels. The device is powered by a 3.3V supply and features an enable/disable function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface mount applications. The component supports an operating temperature range of -40°C to 85°C.

Oscillators Feature Summary

• HCMOS output interface for digital signal compatibility
• Integrated enable and disable control functionality
• Surface-mount design in a leadless SMD package

Oscillators Applications

• Fiber Channel systems
• High-speed digital data transmission circuits
• Communication equipment requiring precise clocking

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 125.000 MHz specification. Confirm the trailing '-TR' indicates tape and reel packaging if bulk handling is needed. Ensure the 3.3V supply voltage aligns with the target system design. Check RoHS compliance status for environmental regulations.

Oscillators Selection Notes

Select this model when a 125 MHz clock source with HCMOS outputs is required. Consider the -40°C to 85°C industrial temperature range for harsh environments. The enable pin allows for dynamic power control. Compare package dimensions against PCB layout constraints before finalizing the design.

Oscillators Part Context

This part belongs to the TSM75 series of high-frequency crystal oscillators. The series covers frequencies from 25 MHz to 125 MHz with similar package and electrical characteristics. Variants differ primarily by frequency suffix and packaging options. The TSM75 line targets demanding communication and computing applications.

Oscillators Replacement Considerations

Direct substitutes include other TSM75-H50CQ33ST variants with different frequency suffixes if the clock rate can be adjusted. Cross-reference with other manufacturers offering 125 MHz HCMOS XO in 4-SMD packages. Verify pinout compatibility and thermal requirements before substitution.
