Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct voltage, frequency, and package variations. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the full part number with authorized distributors to avoid counterfeit components. Ensure the ordering quantity matches the tape and reel specifications if automated placement is required.

Oscillators Selection Notes

Select this component when a 26MHz HCMOS clock source is required within a -40°C to +85°C industrial temperature range. Consider the 2.5V supply constraint and 30mA current draw during power budgeting. The 4-SMD no-lead package necessitates compatible PCB land patterns. Evaluate frequency stability needs against the ±50ppm specification before finalizing the design.

Oscillators Part Context

This part belongs to the TSM32 series of ultra-miniature SMD CMOS oscillators from Transko Electronics. The series offers various frequencies and packages, typically ranging from 2.0x1.6mm to larger sizes. The TSM32 specifically denotes the 3.2x2.5mm footprint family. These oscillators are positioned as drop-in replacements for discontinued legacy models in certain applications, providing modern miniaturization with standard digital outputs.

Oscillators Replacement Considerations

Transko suggests the TMM series as a potential replacement option for discontinued TCXO/VCTCXO lines, though direct substitution requires verification of fit, form, and function against the original design requirements.
