Oscillators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required voltage, stability, and package specifications. Check for recent Product Change Notifications (PCNs) regarding manufacturing updates. Ensure compliance with regional environmental regulations such as RoHS3 before integration into final products.

Oscillators Selection Notes

Select this component when a 1.544 MHz reference signal is required for SDH/SONET applications or similar telecom standards. Consider the ±25 ppm stability requirement against system jitter tolerance. Evaluate the 3.3V supply constraint against available board power rails. The 4-SMD package size must fit within the designated PCB footprint constraints.

Oscillators Part Context

This part belongs to the TA series of MEMS oscillators from TXC Corporation. It shares architectural similarities with other TA-series variants differing primarily in frequency and stability ratings. The series represents a shift from traditional quartz crystals to silicon MEMS solutions for improved reliability and shock resistance in timing applications.

Oscillators Replacement Considerations

The SG-8018CA 1.5440M-TJHSA0 from EPSON is documented as a substitute part number. Verify pinout compatibility and electrical parameter alignment before replacement. Note that the TA-1.544MBD-T is marked as obsolete.
