Oscillators Procurement Notes

Verify the specific suffix (e.g., -TR for tape and reel) against your manufacturing requirements. Confirm that the 1.8V supply voltage aligns with your target circuit design. Ensure the 4-SMD package dimensions fit within your PCB footprint constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a small footprint and low voltage operation are critical. The 40MHz frequency suits standard digital timing needs. Consider the ±25ppm stability requirement against your system's jitter tolerance. Verify thermal performance within the specified -40°C to 85°C range for your application environment.

Oscillators Part Context

This part belongs to the TSM32 series of ultra-miniature CMOS oscillators from Transko Electronics. The series offers various frequencies and voltage options within the same compact 3.2x2.5mm package. It targets applications demanding minimal board space and efficient power usage compared to larger crystal oscillator packages.

Oscillators Replacement Considerations

Check datasheets for compatible parts offering identical 40MHz frequency, 1.8V supply, and 4-SMD no-lead packaging. Verify pinout compatibility and electrical specifications such as current consumption and stability metrics to ensure direct substitution without circuit modification.
