DP83848I PHYTER® — Industrial Temperature Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver May 2008 DP83848I PHYTER® - Industrial Temperature Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver General Description Features The DP83848I is a robust fully featured 10/100 single port Physical Layer device offering low power consumption, including several intelligent power down states. These low power modes increase overall product reliability due to decreased power dissipation. Supporting multiple intelligent power modes allows the application to use the absolute minimum amount of power needed for operation. In addition to low power, the DP83848I is optimized for cable length performance far exceeding IEEE specifications. Low-power 3.3V, 0.18µm CMOS technology Low power consumption < 270mW Typical 3.3V MAC Interface Auto-MDIX for 10/100 Mb/s Energy Detection Mode 25 MHz clock out SNI Interface (configurable) RMII Rev. 1.2 Interface (configurable) The DP83848I includes a 25MHz clock out. This MII Serial Management Interface (MDC and MDIO) means that the application can be designed with a minimum of external parts, which in turn results in the lowest possible total cost of the solution. The DP83848I easily interfaces to twisted pair media via an external transformer and fully supports JTAG IEEE 802.3u MII IEEE 802.3u Auto-Negotiation and Parallel Detection IEEE 802.3u ENDEC, 10BASE-T transceivers and filters IEEE 802.3u PCS, 10...
