Renesas Electronics Corporation Controllers ICS1893BFI

The ICS1893BF is a low-power, integrated physical-layer device (PHY) designed for 10Base-T and 100Base-TX Ethernet applications, compliant with ISO/IEC 8802-3 standards. It operates with a single 3.3V power supply and supports category 5 cables with significant attenuation capabilities. This device features a fully integrated architecture that includes PCS, PMA, and PMD sublayers, along with advanced digital signal processing for enhanced performance. Key functionalities include auto-negotiation with parallel detection, support for both half- and full-duplex modes, and an auto-MDI/MDIX feature that corrects wiring crossover errors. The ICS1893BF is available in a compact 48-pin SSOP package and is suitable for various applications, including NIC cards, PC motherboards, switches, routers, and DSL modems. Its low power consumption, typically around 400 mW, and power-down mode of approximately 21 mW make it an efficient choice for energy-sensitive designs.
