TSM53-H25FM18ST-48.000M

Oscillators Overview

The TSM53-H25FM18ST-48.000M is a miniature surface-mount crystal oscillator manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 48.0000 MHz with a frequency stability of ±25 ppm. The device utilizes HCMOS output logic and functions on a 1.8V supply voltage. It features an enable/disable control function for power management. The component is housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum seated height of 1.30mm.

Oscillators Feature Summary

• Miniature SMD form factor suitable for space-constrained designs
• HCMOS output interface compatible with standard digital logic
• Integrated enable/disable functionality for power optimization

Oscillators Applications

• Portable electronic devices requiring low-power clock sources
• Embedded systems utilizing 1.8V logic levels
• Consumer electronics with strict size limitations

Oscillators Procurement Notes

Verify the specific suffix -TR indicates tape-and-reel packaging when ordering. Confirm that the 1.8V supply requirement aligns with your system's voltage rails. Ensure the HCMOS output voltage levels are compatible with the receiving circuitry inputs to prevent signal integrity issues or damage.

Oscillators Selection Notes

Select this component when a 48 MHz clock source is required in a compact footprint. The ±25 ppm stability suits general timing applications where high precision is not critical. Consider the enable pin if dynamic power saving is necessary. Verify that the 1.8V operating voltage matches the target platform's power distribution network.

Oscillators Part Context

This part belongs to the TSM53 series of miniature oscillators from Transko Electronics. The series offers various frequencies and supply voltages. The TSM53-H25FM18ST variant specifically denotes the 1.8V operation and HCMOS output type within this family of surface-mount timing components.

Oscillators Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 1.8V supply, HCMOS output, and 4-SMD package dimensions. Cross-reference with other manufacturers offering similar miniature XO specifications. Ensure electrical compatibility regarding load capacitance and drive strength before substitution.
