TSM53-H50HM33SN-66.666M

Oscillators Overview

The TSM53-H50HM33SN-66.666M is a miniature surface-mount crystal oscillator manufactured by Transko Electronics, Inc. It operates at a fundamental frequency of 66.666 MHz with an HCMOS output type. The device requires a 3.3V supply voltage and features a frequency stability of ±50ppm. It is housed in a 4-SMD, No Lead package with dimensions of 5.0mm x 3.2mm x 1.3mm. The component supports standard XO functionality and is designed for applications requiring compact form factors.

Oscillators Feature Summary

• Miniature SMD package design suitable for space-constrained layouts
• HCMOS output interface for digital logic compatibility
• Standard XO operation with enable/disable capability

Oscillators Applications

• General purpose clock generation in embedded systems
• Digital signal processing circuits
• Communication modules requiring stable timing references

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure correct frequency tolerance and output drive levels. Confirm that the 4-SMD no-lead footprint matches the target PCB land pattern. Check RoHS compliance status if required by project specifications. Ensure supply voltage requirements align with system power rails before integration.

Oscillators Selection Notes

Select this model when a 66.666 MHz reference with ±50ppm stability is required in a small SMD package. Consider the HCMOS output swing for direct interfacing with compatible logic families. Evaluate thermal performance within the specified operating range. Compare physical dimensions against available board space constraints prior to finalizing the component choice.

Oscillators Part Context

This part belongs to the TSM53 series of miniature oscillators from Transko Electronics. The series utilizes crystal resonators to provide stable frequency outputs. These components are designed as drop-in replacements for various legacy oscillator models discontinued by other manufacturers, offering fit, form, and function compatibility.

Oscillators Replacement Considerations

Transko suggests the TSMV series as a drop-in replacement for Epson Toyocom VG-1201CA models. Verify pinout and electrical parameters match the original design requirements before substitution.
