The reduced schematic diagrams typically detail the following critical subsystems: Raspberry Pi 4 Model B specifications

Because the Ethernet subsystem no longer piggybacks on the USB controller, the Pi 4 achieves true, unthrottled Gigabit speeds. The schematic shows an bus running from the BCM2711 SoC to a Broadcom BCM54213PE Gigabit Ethernet PHY . This transceiver handles the physical layer signals before sending them through the integrated magnetics of the RJ45 jack. 4. Video, Display, and Camera Subsystems

The 40-pin header remains backward-compatible with legacy hardware but introduces expanded multiplexing (muxing) capabilities.
