The KSZ9031RNX is a completely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical layer transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable.
• Single-chip 10/100/1000Mbps IEEE 802.3 compliant Ethernet transceiver
• RGMII timing supports on-chip delay according to RGMII Version 2.0, with programming options for external delay and making adjustments and corrections to TX and RX timing paths
• RGMII with 3.3V/2.5V/1.8V tolerant I/Os
• Auto-negotiation to automatically select the highest link up speed (10/100/1000Mbps) and duplex (half/full)
• On-chip termination resistors for the differential pairs
• On-chip LDO controller to support single 3.3V supply operation – requires only one external FET to generate 1.2V for the core
• Jumbo frame support up to 16KB
• 125MHz reference clock output
• Energy detect power-down mode for reduced power consumption when the cable is not attached
• Energy Efficient Ethernet (EEE) support with low-power idle (LPI) mode and clock stoppage for 100Base-TX/ 1000Base-T and transmit amplitude reduction with 10Base-Te option
• Wake-on-LAN (WOL) support with robust custom-packet detection
• Programmable LED outputs for link, activity, and speed
• Baseline wander correction
• LinkMD TDR-based cable diagnostic to identify faulty copper cabling
• Parametric NAND tree support to detect faults between chip I/Os and board
• Loopback modes for diagnostics
• Automatic MDI/MDI-X crossover to detect and correct pair swap at all speeds of operation
• Automatic detection and correction of pair swaps, pair skew, and pair polarity
• MDC/MDIO management interface for PHY register configuration
• Interrupt pin option
• Power-down and power-saving modes (Continue ...)
• Laser/Network printer
• Network attached storage (NAS)
• Network server
• Gigabit LAN on motherboard (GLOM)
• Broadband gateway
• Gigabit SOHO/SMB router
• IPTV
• IP set-top box
• Game console
• Triple-play (data, voice, video) media center
• Media converter
