Microchip Technology, Inc. Interface - Interface - Drivers, Receivers, Transceivers - KSZ8001LI KSZ8001LI

The KSZ8001LI is a single-chip physical layer transceiver designed for 10/100BASE-TX and 100BASE-FX Ethernet applications. It operates on a 1.8V CMOS design with a total power consumption of 250 mW. The device supports robust operation over standard cables, achieving distances greater than 130 meters. It is compliant with the IEEE 802.3u standard and features auto-negotiation capabilities for 10/100 Mbps speeds, as well as full and half-duplex modes. The KSZ8001LI supports various interfaces, including Media Independent Interface (MII), Reduced MII (RMII), and Serial MII (SMII). It includes a LinkMD¬Æ feature for cable diagnostics with an accuracy of ¬±2 meters, and it supports HP MDI/MDI-X auto crossover. The device can be configured through an MII serial management port or external control pins, and it offers programmable LED outputs for link status, activity, duplex mode, collision, and speed indicators. This transceiver operates with a single 3.3V power supply and includes a built-in 1.8V regulator. It is available in 48-pin LQFP and SSOP packages, making it suitable for various applications, including media converter setups. The operational temperature range is from 0¬8C to 70¬8C for commercial applications and -40¬8C to 85¬8C for industrial applications.
