The device utilizes an HCMOS output type and requires a supply voltage of 3.3V. It features an Enable/Disable function for power management control. The component is available in a 4-SMD, No Lead package configuration.

Oscillators Feature Summary

• HCMOS digital output interface for logic compatibility
• Enable/Disable functionality for power optimization
• Standard crystal resonator base for stable oscillation

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Digital communication interfaces requiring precise clocking

Oscillators Procurement Notes

Verify the specific suffix designation when ordering, as the -TR variant indicates tape and reel packaging while the base model may differ in shipping format. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the 3.3V supply voltage matches your system design constraints before procurement. Check datasheet for absolute maximum ratings to prevent overvoltage damage during integration.

Oscillators Selection Notes

Select this component when a 33.3333 MHz clock source with ±50 ppm stability is required for HCMOS logic circuits. Consider the enable/disable feature if power efficiency is critical for the application. Verify that the 4-SMD surface mount package fits the PCB footprint constraints. Ensure the operating temperature range specified in the official datasheet meets the environmental conditions of the final product deployment.

Oscillators Part Context

This part belongs to the TSM21 series of MEMS-based oscillators from Transko Electronics, designed for compact applications. The series supports frequencies from 1MHz to 137MHz with various SMD packages ranging from 2.0x1.6mm to 7.0x5.0mm.
