• Gaming Consoles

Features:

• Single-Chip 10Base-T/100Base-TX Ethernet Transceiver
• RMII/SNI Interface for MAC Connectivity
• Integrated 1.2V Regulator
• HP Auto-MDIX support
• Energy Detection Mode for Low Power
• Wake-on-LAN (WOL) Support
• Built-in Link Status LEDs Support
• Loopback Modes for Diagnostics
• IEEE 802.3u Compliant

Benefits:

• Simplified Ethernet connectivity allows for easy integration into existing systems.
• Low power consumption extends battery life in portable devices.
• Auto-MDIX eliminates the need for crossover cables.
• Wake-on-LAN support enables remote system wake-up.
• Compact package saves board space.
• Integrated regulator reduces BOM cost and complexity.

Additional Details:

The KSZ8041TLTR supports Reduced Media Independent Interface (RMII) and Serial Network Interface (SNI) for connection to a Media Access Controller (MAC). It incorporates an integrated 1.2V regulator to reduce external component count. The transceiver supports HP Auto-MDIX, automatically configuring the transmit and receive pairs for straight-through or crossover cables. Energy Detection mode reduces power consumption when no link is present. The KSZ8041TLTR is packaged in a small form factor, making it suitable for space-constrained applications. It fully complies with IEEE 802.3u standards for 10Base-T and 100Base-TX Ethernet.
