TSM75-H25FM18ST-40.000M

Oscillators Overview

The TSM75-H25FM18ST-40.000M is a standard crystal oscillator (XO) manufactured by Transko Electronics, Inc., operating at a fixed frequency of 40.000 MHz. It utilizes HCMOS output logic and functions with a supply voltage of 1.8V. The device features an enable/disable control pin for power management. It is housed in a compact 4-SMD, no-lead surface-mount package with dimensions of 0.276 inches in length and 0.197 inches in width. Maximum supply current is specified at 15mA.

Oscillators Feature Summary

• HCMOS output interface compatible with standard digital logic levels
• Integrated enable/disable functionality for active power management
• Compact 4-SMD no-lead surface-mount form factor

Oscillators Applications

• High-speed data handling in FPGA systems
• Timing reference for embedded control systems
• General-purpose clock generation in consumer electronics

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the presence of tape-and-reel packaging versus cut tape or bulk quantities. Ensure the voltage tolerance matches the target circuit requirements. Confirm that the enable pin logic polarity aligns with the system design. Cross-reference the part number against official Transko documentation to validate authenticity and revision status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 40 MHz timing. The HCMOS output ensures compatibility with standard logic families without additional level shifting. Consider the small footprint for space-constrained PCB layouts. Evaluate the enable feature if dynamic power saving is necessary during idle periods in the application lifecycle.

Oscillators Part Context

This oscillator belongs to the TSM75 series from Transko Electronics, designed for surface-mount applications requiring stable clock signals. The series typically offers various frequency options and voltage levels. This specific model targets modern low-power digital designs where size and energy efficiency are critical constraints compared to older through-hole or larger SMD oscillators.

Oscillators Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 1.8V supply, HCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength. Check manufacturer datasheets for equivalent series offerings from other vendors to ensure functional parity.
