KSZ9031RNXIA-puce originale

La description

The KSZ9031RNX is an automotive application interface chip designed and developed by Microchip Semiconductor Corporation. Microchip is one of the main brands of xt-shenzhen. With stable original factory channels, it can provide most of Microchip original electronic components including KSZ9031RNX devices to global customers.

Le KSZ9031RNX is a fully integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical layer transceiver for transmitting and receiving data over standard CAT-5 unshielded twisted pair (UTP) cables. AEC-Q100 qualified for automotive applications, single-chip 10/100/1000 Mbps Ethernet transceiver best suited for IEEE 802.3 applications. RGMII timing support On-chip delay according to RGMII version 2.0 with programming option for external delay and adjustment and correction paths for TX and RX timing。

• RGMII with 3.3V/2.5V/1.8V Tolerant I/O
• Auto-negotiation to automatically select the highest link speed (10/100/1000 Mbit/s) and duplex (half/full)
• On-chip termination resistors for differential pairs
• On-chip LDO controller supports single 3.3V supply operation – requires only one external FET to generate 1.2V for core
• Jumbo frame support up to 16 Ko
• 125 MHz reference clock output
• Energy detect power down mode to reduce power consumption when no cable is connected
• Wake-on-LAN (WOL) with powerful custom packet inspection
• Programmable LED outputs for link, activity and speed
• Baseline drift correction function
• LinkMD TDR-based cable diagnostics to identify faulty copper cabling
• Parametric NAND tree support to detect faults between chip I/O and board
• Loopback mode for diagnostics
• Automatic MDI/MDI-X crossover to detect and correct pair swapping at all speeds
• Automatically detects and corrects for pair swapping, pair skew and pair polarity
• MDC/MDIO management interface for PHY register configuration
• Interrupt pin option
• Power down and power save mode
• Triple play (data, voice, video) media center
• Media Converter KSZ9031RNX Gigabit Ethernet Transceiver with RGMII Support
