Product Introduction
The KSZ8091 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 KSZ8091 is a highly integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, by integrating a low-noise regulator to supply the 1.2V core, and by offering a flexible 1.8/2.5/3.3V digital I/O interface.
The KSZ8091MNX offers the Media Independent Interface (MII) and the KSZ8091RNB offers the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII-compliant Ethernet MAC processors and switches.
Energy Efficient Ethernet (EEE) provides further power saving during idle traffic periods and Wake-on-LAN (WOL) provides a mechanism for the KSZ8091 to wake up a system that is in standby power mode.
The KSZ8091 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 KSZ8091 I/Os and the board. LinkMD TDR-based cable diagnostics identify faulty copper cabling.
The KSZ8091MNX and KSZ8091RNB are available in 32-pin, lead-free QFN packages.
