Oscillators Procurement Notes

Verify that the specific part number includes the '-TR' suffix to confirm tape-and-reel packaging if required for automated assembly processes. Ensure the 1.8V supply voltage aligns with the target system's power rails. Confirm that the ±20ppm frequency stability meets the application's timing accuracy requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V HCMOS oscillator is needed for 32.768 kHz timing applications. Consider the ±20ppm stability and -40°C to +85°C temperature range for environmental suitability. Evaluate the 200µA current draw against system power budgets. Compare physical dimensions against available PCB footprint constraints to ensure mechanical fit.

Oscillators Part Context

This oscillator belongs to Transko's TSL series of MEMS-based oscillators, which offer alternatives to traditional ceramic resonators. The TSL32 model specifically targets applications requiring small form factors and low power operation. It serves as a drop-in replacement for certain discontinued models from other manufacturers, providing fit, form, and function compatibility in existing designs.

Oscillators Replacement Considerations

Transko suggests the TMM series as a potential alternative for broader frequency ranges. For specific discontinued models like Epson VG-1201CA or Citizen CS10, Transko offers dedicated replacements such as TSMV or CS63B respectively. Verify pinout and electrical specifications when substituting with these or other family members.
