efficient signaling scheme required by automotive applications. The BroadR-Reach automotive
Ethernet standard uses a signaling scheme with higher spectral efficiency than that of 100BASE-TX. This limits the signal bandwidth of Automotive Ethernet to 33.3 MHz, which is about half the bandwidth of 100BASE-TX. A lower signal bandwidth improves return loss, reduces crosstalk, and ensures that BroadR-Reach automotive Ethernet standard passes the stringent automotive electromagnetic emission requirements.

This allows automotive manufacturers to incorporate multiple electronic systems and devices, such as advanced safety features (i.e. 360-degree surround view parking assistance, rear-view cameras and collision avoidance systems) and comfort and infotainment features. The automotive-qualified BroadR-Reach Ethernet physical layer standard can be combined with
