It integrates 2 10\/100\/1000BASE-T PHY ports with 3 RGMII\/xMII and 2 SerDes\/SGMII MAC-side ports, enabling flexible multi-port network topologies. The 88E6320 is the cost-optimized variant that excludes TCAM, Synchronous Ethernet, and cut-through switching available in the 88E6321. With 1Mbit packet memory, 8K MAC address table, and 4-level per-port QoS, it supports Audio\/Video Bridging (AVB) and Energy Efficient Ethernet for power-sensitive applications.","working_principle":"The 88E6320 operates as a Layer 2 Ethernet switch with store-and-forward architecture. Incoming frames from any of the 7 ports are buffered in the 1Mbit shared packet memory. The switching engine performs MAC address lookup against the 8K-entry table to determine the output port(s). Frames are queued at the output port with 4-level QoS classification based on VLAN priority, DSCP, or port-based rules. The integrated PHYs handle 10\/100\/1000BASE-T physical layer encoding\/decoding, auto-negotiation, and EEE power management. RGMII\/xMII ports connect to external MACs (CPUs, SoCs), while SerDes\/SGMII ports support fiber or backplane connections. Management is performed via MDIO interface to the embedded switch CPU.","pin_description":"
