The KSZ9477STXI-TR is a highly-integrated, 7-port Layer-2 managed Gigabit Ethernet switch designed for robust industrial networking. It incorporates five 10/100/1000BASE-T PHY ports, one SGMII MAC port, and one configurable RGMII/MII/RMII MAC port for flexible connectivity to a host processor or another switch. The device provides a non-blocking, wire-speed switching fabric and supports advanced features such as full VLAN and QoS, Access Control List (ACL) filtering, and ring redundancy protocols like DLR and HSR. As part of the EtherSynch® family, it offers full hardware support for IEEE 1588v2 Precision Time Protocol (PTP) and IEEE 802.1AS Audio Video Bridging (AVB) for time-sensitive applications. With a supported industrial temperature range, it is ideal for industrial control, automation switches, and networked measurement systems.
