Oscillators Procurement Notes

Verify the specific suffix TCHSA0 matches the required pin configuration and tape-and-reel quantity. Confirm that the 99.99 MHz frequency aligns with the target circuit design requirements. Ensure the 1.8V to 3.3V supply voltage compatibility exists within the host system power rails. Check for any specific RoHS or environmental compliance documentation if required by the end product regulations.

Oscillators Selection Notes

Select this component when a stable 99.99 MHz reference is needed with tight phase noise specifications. Consider the 4-SMD footprint for space-constrained PCB layouts. Evaluate the +/-20 ppm accuracy against system jitter budgets. The wide industrial temperature range makes it suitable for automotive or outdoor applications where thermal stability is critical.

Oscillators Part Context

This part belongs to the SG-8101CB series of standard XO oscillators. The series offers various frequency options while maintaining consistent electrical characteristics and package dimensions. It serves as a direct replacement for older HC-49/U style crystals in modern surface-mount designs, providing improved performance and easier assembly integration.

Oscillators Replacement Considerations

Direct substitutes include other SG-8101CB variants with identical pinouts but different frequencies. Cross-reference with Epson's official substitution guide for equivalent performance metrics. Verify that alternative sources maintain the same 4-SMD no-lead package profile to ensure mechanical fit.
