TSM32-H25HM33ST-45.158M-TR

Oscillators Overview

The TSM32-H25HM33ST-45.158M-TR is a surface-mount crystal oscillator (XO) manufactured by Transko Electronics, Inc., operating at a nominal frequency of 45.158 MHz. It utilizes HCMOS output logic and functions on a 3.3V supply voltage with a maximum current consumption of 30mA. The device features an enable/disable control function and offers a frequency stability of ±25ppm. Designed for commercial temperature ranges from 0°C to 70°C, it is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 1.20mm.

Oscillators Feature Summary

• Ultra-miniature SMD form factor suitable for space-constrained designs
• HCMOS output signal compatibility with standard digital logic
• Integrated enable/disable functionality for power management

Oscillators Applications

• General-purpose clock generation for embedded systems
• Timing reference for microcontrollers and processors

Oscillators Procurement Notes

Verify the complete part number including the trailing -TR suffix to confirm tape-and-reel packaging configuration. Ensure the specific frequency variant matches the system requirement, as the TSM32 series supports multiple frequencies. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Oscillators Selection Notes

Select this component when a small footprint and low power consumption are critical constraints. The 3.3V operation aligns with modern low-voltage logic families. Consider the ±25ppm stability specification against the target application's timing tolerance requirements. The enable pin allows for dynamic power savings during idle periods, making it suitable for battery-operated devices requiring efficient energy usage.

Oscillators Part Context

This oscillator belongs to the TSM32 series, characterized by its ultra-miniature 3.2 x 2.5 mm package size. The series provides various frequency options within a standardized physical envelope, facilitating design reuse across different product lines. The TSM32 family targets applications demanding high reliability and minimal board space utilization in consumer electronics and industrial equipment.

Oscillators Replacement Considerations

Direct substitutes must match the 45.158 MHz frequency, HCMOS output, 3.3V supply, and 4-SMD package dimensions. Verify that alternative sources offer identical ±25ppm stability and enable/disable functionality. Check for equivalent thermal and electrical specifications to ensure seamless integration without circuit modification.
