The BCM89890 is a highly integrated, single-port, Gigabit Ethernet (GbE) transceiver chip designed by Broadcom. It's commonly used in various applications, including:
is a foundational component for the next generation of vehicle architectures: bcm89890
: Facilitates rapid V2X (Vehicle-to-Everything) communications for smart mobility. Development and Testing Tools significantly lowering radiated emissions
Traditional 100BASE-TX uses a PAM-5 (Pulse Amplitude Modulation 5-level) scheme over two pairs. The BCM89890 uses signaling over a single pair. This reduces the signal bandwidth from 125 MHz to just 33 MHz, significantly lowering radiated emissions, which is a primary concern in noise-sensitive automotive cabins. bcm89890
