Supply [Microchip] Ethernet Transceivers: Supply KSZ9031RNXIC Gigabit Ethernet Physical Layer Transceiver

Supply [Microchip] Ethernet Chip

KSZ9031RNXIC is a completely integrated triple-speed (10BASE-T/100BASE-TX/1000BASE-T) Ethernet physicallayer transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable.

Product Features

• Single-chip 10/100/1000Mbps IEEE 802.3 compliant Ethernet transceiver
• KSZ9031Mxx feature GMII/MII standard interface with 3.3V/2.5V/1.8V tolerant I/Os
• KSZ9031Rxx feature 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
• GMII/MII/RGMII with 3.3V/2.5V/1.8V tolerant I/Os
• Auto-negotiation to automatically select the highest linkup 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
• Wake-on-LAN (WOL) support with robust custom-packet detection
• AEC-Q100 qualified for automotive applications (KSZ9031RNXUB-VAO, KSZ9031RNXVB-VAO)
• 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
• Core (DVDDL, AVDDL, AVDDL_PLL): 1.2V (external FET or regulator)
• VDD I/O (DVDDH): 3.3V, 2.5V, or 1.8V
• Transceiver (AVDDH): 3.3V or 2.5V (commercial temp)
