TSM75-H50CQ33ST-12.000M

Oscillators Overview

The TSM75-H50CQ33ST-12.000M is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc., operating at a fixed frequency of 12.000 MHz. It utilizes HCMOS output logic levels and functions as a clock source for digital circuits. The device supports a supply voltage of 3.3V and includes an enable/disable control function to manage power consumption. It is housed in a compact 4-SMD, No Lead surface-mount package, designed for integration into space-constrained electronic assemblies requiring precise timing signals.

Oscillators Feature Summary

• HCMOS output interface for digital compatibility
• Integrated enable/disable control functionality
• Surface-mount 4-SMD no-lead package design

Oscillators Applications

• General-purpose clock generation for microcontrollers
• Timing reference for digital signal processing systems
• Clock source for communication interface modules

Oscillators Procurement Notes

Verify the specific suffix 'ST' against the manufacturer's current datasheet to confirm pinout orientation and tape/reel specifications. Ensure the 3.3V supply requirement aligns with the target system voltage rails. Confirm RoHS compliance status if environmental regulations are mandatory for the end product. Cross-reference the 12.000 MHz frequency tolerance requirements with the application's timing sensitivity needs before finalizing procurement.

Oscillators Selection Notes

Select this component when a standard HCMOS output is required for 12 MHz applications. The 3.3V operating voltage makes it suitable for modern low-voltage logic families. The enable/disable feature allows for dynamic power management in battery-operated devices. Consider the 4-SMD package size for PCB layout constraints compared to larger through-hole alternatives.

Oscillators Part Context

This part belongs to the TSM75 series of crystal oscillators from Transko Electronics. The series offers various frequencies and output types. The 'H50' designation typically relates to the series characteristics, while 'CQ33' indicates the 3.3V supply and specific package type. The 'ST' suffix distinguishes the specific variant within the 12 MHz frequency option.

Oscillators Replacement Considerations

Direct substitutes include other 12 MHz HCMOS oscillators in 4-SMD packages from manufacturers like Stanley or Epson, provided electrical parameters match. Verify that replacement parts support the same enable/disable control logic and 3.3V supply range to ensure functional compatibility without circuit modification.
