The device integrates five 10\/100 Ethernet PHY transceivers, MACs, and a non-blocking switching fabric in a single chip, providing a complete 5-port switch solution with no external PHY required. It supports IEEE 802.1Q VLAN, port-based VLAN, 4 priority queues per port with strict priority scheduling, and auto-MDIX on all ports. An MDIO management interface allows configuration of advanced features. The device operates from 3.3V with 1.0V core supply and is designed for unmanaged switch applications in home, SOHO, and industrial networking.","working_principle":"The IP175DLFI integrates all Ethernet switch functions in a single chip. (1) PHY: Each of the five ports includes a 10\/100 Ethernet PHY that handles physical layer encoding\/decoding (4B\/5B, MLT-3 for 100BASE-TX; Manchester for 10BASE-T), auto-negotiation, and auto-MDIX. (2) MAC: Each port MAC handles frame reception, CRC checking, frame transmission, and flow control (IEEE 802.3x). (3) Switching Fabric: A non-blocking shared-memory switching fabric forwards frames between ports at wire speed. The 128KB packet buffer handles burst traffic. (4) Address Table: A 1K-entry MAC address table is learned automatically and supports aging. (5) VLAN: Port-based and 802.1Q tag-based VLAN provide network segmentation. (6) QoS: Four priority queues per port with strict priority scheduling ensure low-latency for high-priority traffic.","pin_description":"
