1894K-40LF General Description

The IDT1894-40 is a revolutionary low-power PHY device that supports the ISO/IEC 10Base-T and 100Base-TX Ethernet standards, catering to the needs of MII, Node applications requiring the Auto-MDIX feature for automatic correction of crossover errors in plant wiring. With its Digital-Signal Processing (DSP) control in the Physical-Medium Dependent (PMD) sublayer, the IDT1894-40 enables the transmission and reception of data on unshielded twisted-pair (UTP) category 5 cables with attenuation in excess of 24 dB at 100MHz, effectively eliminating errors from killer packets. Its Serial-Management Interface facilitates the exchange of command and status information, enhancing monitoring and control capabilities. Furthermore, the IDT1894-40's Media-Dependent Interface (MDI) can be configured for half- or full-duplex operation at data rates of 10 Mb/s or 100Mb/s, providing flexibility for a range of networking applications. Additionally, the device features a programmable interrupt output function, allowing for efficient notification of specific events via interrupt, rather than polling. With its wide range of applications including NIC cards, PC motherboards, switches, routers, DSL and cable modems, game machines, printers, network-connected appliances, and industrial equipment, the IDT1894-40 is a versatile and reliable solution, setting a new standard for PHY devices
