Microchip | KSZ8001LI-TR

The KSZ8001LI TR is a 10BASE-T/100BASE-TX/100BASE-FX physical layer transceiver, available in surface mount LQFP-48 package.

This device operating the core at 1.8 volts to meet low voltage and low power requirements. The solution provides MII/RMII/SMII interfaces to transmit and receive data. A unique mixed-signal design extends signaling distance while reducing power consumption.

Features:

• Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution
• 1.8V CMOS design, power consumption 250 mW
• Robust (130m+) operation over standard cables
• Supports Media Independent Interface (MII), Reduced MII (RMII), and Serial MII (SMII)
• LinkMD feature to determine cable length and diagnose faulty cables up 200 m with +/- 2 m accuracy
• Supports HP MDI/MDI-X auto crossover
• Supports power down mode and power saving mode
• MDC/MDIO to 12.5 MHz for rapid configuration
• Fully compliant to IEEE 802.3u standard
• Supports auto-negotiation and manual selection for
• 10/100Mbps speed and full / half-duplex mode
• Configurable through MII serial management port or via external control pins
