NOTE: - Re-check FL1 with TJA1100 datasheet or design that this part is ok.
Slightly different part number from the previous schematic (ACT45L-101-2P)
-The L is the ethernet version, and the B is CAN version.
It may still be allowed - need to check with the BL

NOTE: Review app note or have apps engineer look at the. AN

for TJA1101 shows additional ferrite and filtering for VDDA, VBAT and other signals.
Could add optional components in case they are needed for EMI mitigation.

NOTE: App note for TJA1100 shows optimal protection diode layout
