DP83848MPHPREP

The Texas Instruments® DP83848MPHPREP is an integrated physical layer adapter designed for use in providing high-performance, cost-effective, and secure communication over twisted-pair wire (e.g., Category 5/5e/6 cabling), coaxial cable, and wireless networks. It is [an advanced] universal transceiver with a wide range of applications, including operation with high-speed 10BASE-T Ethernet and 1000BASE-T (gigabit) on copper cables, Application Specific Standard Products (ASSPs) and high-speed communications (e.g., gigabit networks).

Application Field

DP83848MPHPREP is designed to bridge the gap between various physical media. It supports auto-negotiation of both 10BASE-T and 1000BASE-T networking technologies, thus allowing the same device to be used in both legacy and next-generation applications. It also supports a wide variety of network speeds, ranging from 10Mb/s up to 1.25Gb/s.

DP83848MPHPREP is especially well suited for applications in which both twisted pair and fiber optic media must be used in parallel. This includes applications such as wireless access points and wireless bridges, as well as enterprise-class networks in which multiple connections are required, such as 10BASE-T (or Fast Ethernet) and 1000BASE-T Ethernet. Additionally, the DP83848MPHPREP can be used as a drive for Gigabit Ethernet, Fast Ethernet, and HomePNA networks.

Furthermore, DP83848MPHPREP is an ideal solution for applications requiring advanced testing capabilities. It is designed to include an extensible development environment and comprehensive debugging facilities, including integrated test functions and analysis tools. This makes it an attractive solution for complex network implementations.
