TSM75-H50CQ33ST-66.000M

Oscillators Overview

The TSM75-H50CQ33ST-66.000M is a 66 MHz crystal oscillator (XO) manufactured by Transko Electronics, Inc. It features HCMOS output logic and operates on a 3.3V supply voltage. The device includes an enable/disable function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm. The unit supports surface mount installation and is designed for standard timing applications requiring precise frequency generation.

Oscillators Feature Summary

• HCMOS output signal compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD no-lead surface mount packaging

Oscillators Applications

• General digital system clocking
• Embedded microcontroller timing sources
• Standard communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct frequency tolerance and operating temperature range specifications. Confirm that the 4-SMD package dimensions align with your PCB footprint requirements. Ensure the 3.3V supply voltage matches your system design constraints before procurement.

Oscillators Selection Notes

Select this component when a standard HCMOS output is required at 66 MHz with low profile surface mount capabilities. Consider the enable/disable feature if power efficiency during idle states is a design priority. Verify that the ±50ppm stability meets your system's jitter and timing accuracy requirements compared to higher precision alternatives.

Oscillators Part Context

This part belongs to the TSM75 series of MEMS-based oscillators from Transko Electronics. The series offers various frequencies within the 1MHz to 137MHz range. These devices are positioned as drop-in replacements for legacy ceramic oscillators, providing improved reliability and performance in modern electronic designs requiring stable clock signals.

Oscillators Replacement Considerations

Transko suggests the TMM series as potential replacements for discontinued TCXO/VCTCXO models. For general XO needs, verify direct pin-to-pin compatibility with existing designs.
