We used NXP's SJA11105 switch product and found that using the same electrical route as SJA1105QELY communicated normally, while using SJA1105TELY when the communication lost packet. Please explain specifically the difference between SJA1105TELY and SJA1105QELY.
hello,
SJA1105QELY https://www.nxp.com/docs/en/data-sheet/SJA1105PQRS.pdf
SJA1105TELY https://www.nxp.com/docs/en/data-sheet/SJA1105.pdf
The SJA1105 is an IEEE 802.3-compliant 5-port automotive Ethernet switch.
The SJA1105P/Q/R/S safe and secure automotive gigabit Ethernet switch family extends the capabilities of the SJA1105/SJA1105T [1] switches with improved security-related features, extended interface options, and ISO 26262 ASIL-A compliance.
SJA1105QEL is pin compatible with SJA1105 and SJA1105T and both has TT and TSN features (SJA1105/Q/S only). For more details you can compare datasheets (links above).
Have a nice day
