Oscillators Procurement Notes

Verify the specific ordering suffix matches the required frequency and tolerance before procurement. Confirm that the 3.3V supply voltage aligns with your system design constraints. Ensure the 4-SMD package dimensions fit within your board layout restrictions. Check for any recent product lifecycle updates or discontinuation notices from the manufacturer prior to placing orders.

Oscillators Selection Notes

Select this component when a precise 32.768 MHz reference is needed for timekeeping or synchronization tasks. Consider the ±30ppm stability requirement against your system's timing accuracy needs. Evaluate the 40mA current draw against your power budget constraints. Ensure compatibility with 3.3V logic families due to the HCMOS output type.

Oscillators Part Context

This oscillator belongs to Transko's TSM53 series of miniature SMD oscillators. The series offers various frequencies and packages, typically ranging from 2.0x1.6mm to larger footprints. These components are designed as drop-in replacements for discontinued parts 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 MEMS-based applications. For general oscillator replacements, verify pinout and electrical specifications match exactly. No direct substitute part numbers are explicitly confirmed for this specific model in public documentation.
