100BASE-T1 /1000BASE-T1 Single-Port Automotive Ethernet Transceiver

Currently Viewing:

The Broadcom BCM8988x is a 100BASE-T1/1000BASE-T1 Ethernet transceiver device designed for automotive applications including in-vehicle connectivity, infotainment, ADAS and smart mobility. The device performs all the physical layer (PHY) functions for 100BASE-T1 and 1000BASE-T1 encoded Ethernet packets over a single pair of unshielded twisted-pair (UTP) cables. The BCM8988x is designed to meet automotive specifications for EMI/EMC, noise cancellation, and transmission jitter, providing consistent and reliable operation over a single unshielded twisted-pair automotive cable.
