TheKSZ9031MNXIC is a single port Fast Ethernet Physical Layer Transceiver, designed for use with both 100BASE-TX and 10BASE-T standards. It integrates advanced features such as Wake-on-LAN, Energy Efficient Ethernet (EEE), Auto-MDIX, low power CMOS operation and Transmit/Receive Autonegotiation.

The KSZ9031MNXIC has a number of applications and is widely used for applications such as routers, hubs, switches, access points, gateways, TCP/IP applications, Ethernet bridges/repeaters/converters, as well as ethernet to WAN/LAN/VLAN Bridges. It is also used in industrial and security applications such as asset tracking, alarm systems, surveillance and home automation.

The KSZ9031MNXIC works on the principle of receiving, transmitting and encoding data transmitted over a communication interface. The device supports 45 Mbps (DMA mode) of peak network data transfer speeds. It uses a 15-pin connector to make connections to Ethernet cables. The pins are divided into power, speed, and link control pins, which are used to detect the current connection status. The power pins must remain connected at all times, as the power requirement for the device is higher than 5V.

The device is built with an onboard clock frequency of 25 MHz and a data bus width of 16 bits. It operates on a 0V to 4.3V power supply with a temperature operating range of 0°C to +85°C. The device features a flexible, integrated solution for IEEE Std 802.3 across twisted pair cables, supporting both 10BASE-T and 100BASE-TX. It automatically detects and configures itself to the connected network’s speed and mode without any user intervention. It also provides Wake on LAN (WoL) support, which enables the system to power up when the LAN connection is active.

The KSZ9031MNXIC includes a CRC engine and scrambler/descrambler for error detection and correction. It automatically adjusts data transmission speed to minimize errors. The device supports full-duplex operation, half-duplex operation, queue arbitration, flow control, and link control. The KSZ9031MNXIC supports a wide range of features to improve performance, such as Auto-Negotiation and Auto-MDIX, which allow the device to detect the type of cable connected and adjust the output current accordingly.

In short, the KSZ9031MNXIC is a single port Fast Ethernet Physical Layer Transceiver designed for use with both 100BASE-TX and 10BASE-T standards. It is a highly versatile device used for a wide range of applications, from router and hub design, to industrial and security applications. It is a low power, efficient device with integrated features such as Wake-on-LAN, Energy Efficient Ethernet (EEE), Auto-MDIX, and Transmit/Receive Autonegotiation.
