The KSZ8041FTLI-TR is an integrated single chip physical layer device specifically designed for use in Ethernet-based microcontroller (MCU) applications. It contains all components necessary to implement a complete 10 Mbps Ethernet physical layer, including a 5.0V operating voltage regulator, a high speed differential line transceiver, clock and data recovery circuitry, an auto-negotiation controller, and clock synthesis circuitry. The device is very well suited for both full and half duplex applications, and supports speeds of 10 Mbps full duplex, 20 Mbps full duplex, and 10 Mbps half duplex.

The KSZ8041FTLI-TR is designed to run at 10 Mbps in full duplex mode with autonegotiation enabled and is compatible with the IEEE 802.3, 802.3u and 802.3x specifications. It is powered by a 12V input, which is regulated to 5.0V output. The device provides two independent output signals with selectable voltage swing, each tailored to specific components such as 10/100/1000 MACs and PHYs. The flexibility of the KSZ8041FTLI-TR\'s features enables it to be used in a variety of Ethernet applications, including server, workstation, storage, and embedded applications.

The KSZ8041FTLI-TR is a single-chip Ethernet physical layer transceiver and copper interface for network interface cards, Ethernet switches and routers, and other products. Its power efficient design and low-voltage operating capabilities make it suitable for a wide range of applications. The device includes both 5-volt and 3.3-volt power supply options, and the ability to auto-sense and configure the link as either full-duplex or half-duplex.

The core of two-channel serial Physical Coding Sublayer (PCS) and 10 Mbps Medium Independent Interface (MII) of the KSZ8041FTLI-TR enables it to detect and configure the speed (full-duplex or half-duplex) and type of +5V link partner as well as to detect and distinguish different link partner types (adaptive or fixed-rate) and bit rate. A clock jumpers selection allows the user to adjust the transmit and receive line clocks to optimize performance, allowing the device to adjust to changing conditions and speeds.

The KSZ8041FTLI-TR supports one integrated Twisted-Pair Physical Coding Sublayer (TP-PCS) channel on the chip, providing single-chip connectivity to the media. The integrated Twisted pair-PCS channel provides a simple, cost-effective solution for Ethernet network interface application. The device supports both Media Dependent Interface (MDI) and Media Independent Interface (MII) compliance. The TP-PCS meets the IEEE 802.3z standard and provides full-duplex or half-duplex operation at 10 Mbps and is compatible with both shielded and unshielded media.

In addition, the KSZ8041FTLI-TR supports 10 Mbps operation with support for 802.3z. The integrated auto-negotiation logic supports multiple operating modes such as full-duplex (10 Mbps), half-duplex (10 Mbps), half-duplex (2.5 Mbps), auto-negotiate (1000 Mbps), flex-mode (10/100/1000 Mbps) and multiple languages for auto-negotiate commands. The device is also compliant with the IEEE1588 version 2.0 standard and supports IEEE 802.3az Energy Efficient Ethernet (EEE) for improved power management. The device supports both legacy 10/100/1000 BaseT Ethernet and MAC-level flow control.

All in all, the KSZ8041FTLI-TR is a versatile, single-chip 10 Mbps transceiver. Its low-voltage design and power efficient design make it ideal for a range of Ethernet applications such as switches, routers, and network interface cards. The integrated single-chip solution is highly cost-effective, and the device supports multiple operating modes, as well as network and media interfaces for efficient data transfer. The flexibility and scalability of the device ensure that it is well-suited for a variety of Ethernet applications.
