TSM21-H50CQ33ST-10.000M

Oscillators Overview

The TSM21-H50CQ33ST-10.000M is an ultra-miniature surface-mount crystal oscillator manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 10.000 MHz with HCMOS output logic levels. The device requires a 3.3V supply voltage and features an enable/disable control function for power management. It utilizes a standard crystal resonator base and offers a frequency stability of ±50 ppm. The component is housed in a compact 4-SMD, no-lead package measuring 2.0 x 1.6 x 0.9 mm, designed for space-constrained electronic applications requiring precise timing signals.

Oscillators Feature Summary

• Ultra-miniature SMD form factor suitable for dense PCB layouts
• HCMOS output interface compatible with standard digital logic
• Integrated enable/disable pin for active power control
• Standard crystal resonator base ensuring reliable frequency generation

Oscillators Applications

• Portable consumer electronics requiring low profile components
• Communication modules needing stable clock references
• Embedded systems with strict spatial constraints
• Digital signal processing circuits

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure correct voltage, frequency, and package variations. Confirm that the HCMOS output type matches system logic requirements. Check for any environmental or reliability certifications required for the target application before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a 10 MHz clock signal is required in a minimal footprint. Ensure the 3.3V supply rail is stable and within specified limits. Consider the ±50 ppm stability requirement against system timing tolerances. Verify that the enable/disable functionality aligns with power sequencing needs.

Oscillators Part Context

This part belongs to the TSM21 series of ultra-miniature oscillators from Transko Electronics. The series includes various frequencies and output types, all sharing the same compact 2.0 x 1.6 x 0.9 mm package. It is distinct from larger packages like the TPS series which offer different output formats such as LVPECL.

Oscillators Replacement Considerations

Direct substitutes must match the 10 MHz frequency, 3.3V HCMOS output, and 4-SMD no-lead package dimensions. Cross-reference with other manufacturers offering similar ultra-miniature XO specifications if availability is an issue.
