KSZ9477STXI-TR General Description
The KSZ9477 is a fully integrated layer 2, managed, seven-port gigabit Ethernet switch with numerous advanced features. Five of the seven ports incorporate 10/100/1000 Mbps PHYs. The other two ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY. The SGMII port may interface to a fiber optic transceiver.
Full register access is available by SPI or I2C interfaces, and by optional in-band management via any of the data ports. PHY register access is provided by a MIIM interface.
Security features include support for IEEE 802.1X port-based authentication and Access Control List (ACL) filtering.
As a member of the EtherSynch® product family, the KSZ9477 incorporates full hardware support for the IEEE 1588v2 Precision Time Protocol (PTP), including hardware time-stamping at all PHY-MAC interfaces, and a high-resolution hardware “PTP clock”. IEEE 1588 provides sub-microsecond synchronization for a range of industrial Ethernet applications.
The KSZ9477 supports time-stamping and time-keeping features support IEEE 802.1AS time synchronization. All ports feature credit based traffic shapers for IEEE 802.1Qav.
The KSZ9477 also incorporates features that simplify the implementation of DLR and HSR redundancy protocols by off-loading tasks from the host processor. For DLR networks, these features include Beacon frame generation, Beacon timeout detection, and MAC table flushing. HSR networks are supported with automatic duplicate frame discard, and self-address filtering.
An assortment of power-management features including Energy-Efficient Ethernet (EEE) have been designed in to satisfy energy efficient environments.
