TSM53-H25HM33RT-40.000M

Oscillators Overview

The TSM53-H25HM33RT-40.000M is a miniature surface-mount crystal oscillator (XO) manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 40.000 MHz with HCMOS output logic levels. The device is powered by a 3.3V supply and features an enable/disable control function for power management. It utilizes a 4-SMD, no-lead package with dimensions of 3.2mm x 2.5mm x 1.2mm. The component supports a maximum supply current of 30mA and maintains a frequency stability of ±25ppm over the operating temperature range of 0°C to 70°C.

Oscillators Feature Summary

• HCMOS output signal compatibility
• Integrated enable and disable control functionality
• Miniature surface-mount form factor

Oscillators Applications

• General-purpose digital clock generation
• Embedded system timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify that the specific part number matches the required frequency and voltage specifications before procurement. Confirm that the supplier provides official datasheets to ensure compliance with RoHS3 standards and moisture sensitivity level requirements. Ensure that the ordering suffix corresponds to the correct packaging format if reel quantities are necessary for automated assembly processes.

Oscillators Selection Notes

Select this component when a compact, low-power HCMOS oscillator is required for 3.3V logic systems. Consider the ±25ppm frequency stability and 0°C to 70°C operating range against application environmental constraints. Evaluate the 4-SMD package size against available PCB real estate and verify that the enable/disable feature aligns with system power management strategies.

Oscillators Part Context

This model belongs to the TSM53 series of miniature SMD oscillators from Transko Electronics, Inc. The series is characterized by small physical dimensions and standard HCMOS/TTL output compatibility. It serves as a direct replacement for larger through-hole or older surface-mount oscillator technologies in space-constrained electronic designs requiring stable clock signals.

Oscillators Replacement Considerations

Direct substitutes within the same family include variants with different frequencies such as TSM53-H25HM33RT-28.63636M. Cross-model replacements require verification of pinout compatibility, voltage levels, and output logic types to ensure functional equivalence in the target circuit.
