Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix CEL/1Y against official NXP documentation to confirm pinout and packaging details. Confirm moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with the intended host processor interface, such as SPI for firmware loading or SABRE connectors for direct integration with S32G or i.MX platforms.

Analog Switches - Special Purpose Selection Notes

Select this model for automotive networks requiring integrated PHYs and TSN compliance. Consider the SJA1110-EVM for initial evaluation of cascaded configurations and software integration. Verify that the required number of 100BASE-T1 ports aligns with the specific variant's physical port count. Ensure the design supports the necessary power management solutions, such as 12V, 24V, or 48V System Basis Chips.

Analog Switches - Special Purpose Part Context

The SJA1110 series serves as a multi-gigabit safe and secure TSN Ethernet switch with integrated 100BASE-T1 PHYs. It is part of NXP's automotive connectivity portfolio, often paired with processors like the S32G vehicle network processors or i.MX application processors. The series supports ASIL D safety levels and hardware security engines for robust automotive cybersecurity.

Analog Switches - Special Purpose Replacement Considerations

Check for updated revisions within the SJA1110 family. Verify if alternative suffixes offer different packaging or temperature grades. Consult NXP for cross-reference availability if the specific CEL/1Y variant is discontinued.
