Add To BomKSZ8721BL-TR General Description
Operating at 2.5 volts to meet low voltage and low power requirements, the KSZ8721 is a 10BaseT/100BaseTX/FX Physical Layer Transceiver, which provides an MII and RMII host interface to transmit and receive data.
It contains the 10BaseT Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sub-layer (PCS) functions. Moreover, the KSZ8721 has on-chip 10BaseT output filtering, which eliminates the need for external filters and allows a single set of line magnetics to be used to meet requirements for both 100BaseTX and 10BaseT.
The KSZ8721 can automatically configure itself for 100 or 10 Mbps and full or half duplex operation, using on-chip Auto-Negotiation algorithm. It is an ideal choice of physical layer transceiver for 100BaseTX/10BaseT an 100BaseFX applications.
