Description

ENET TRANSCEIVER 100MBPS 0 TO 70DEG C
The KSZ8081 is a single-supply 10Base-T/100Base-TX Ethernet physical-layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ8081 is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs and by integrating a low-noise regulator to supply the 1.2V core. The KSZ8081MNX offers the Media Independent Interface (MII) and the KSZ8081RNB offers the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII-compliant Ethernet MAC processors and switches. A 25MHz crystal is used to generate all required clocks, including the 50MHz RMII reference clock output for the KSZ8081RNB. The KSZ8081 provides diagnostic features to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between KSZ8081 I/Os and the board. Micrel LinkMD® TDR-based cable diagnostics identify faulty copper cabling. The KSZ8081MNX and KSZ8081RNB are available in 32- pin, lead-free QFN packages (see “Ordering Information”).
