DP83848YB

The DP83848YB from National Semiconductor is an active, extended temperature, 10/100-Mbps Ethernet PHY transceiver with JTAG support. It is designed for robust performance in demanding environments, operating from -40°C to 125°C.

This device supports multiple interface types including MII, RMII (Rev. 1.2), and SNI, offering flexibility in system design. It features a typical I/O supply voltage of 3.3V and consumes less than 270 mW of power. Key electrical features include Auto-MDIX for 10/100 Mb/s, Energy Detection Mode, and a 25-MHz clock output.

The DP83848YB complies with various IEEE standards, including 802.3 MII, 802.3 Auto-Negotiation, 10BASE-T, and 100BASE-TX. It also incorporates IEEE 1149.1 JTAG support and an ANSI X3.263 compliant TP-PMD physical sub-layer with adaptive equalization. Error-free operation is supported up to 150 meters.

Packaged in a 48-pin HLQFP, the DP83848YB includes programmable LED support for link, activity, duplex, and collision detection. It also features a 10/100 Mb/s Packet BIST for built-in self-testing, making it suitable for a wide range of networking applications.
