Description

The number of applications requiring Ethernet connectivity continues to increase, driving Ethernet enabled

devices into harsher environments.

The DP83848C/I/VYB/YB was designed to meet the challenge of these new applications with an extended

temperature performance that goes beyond the typical Industrial temperature range. The

DP83848C/I/VYB/YB is a highly reliable, feature rich, robust device which meets IEEE 802.3 standards

over multiple temperature ranges from commercial to extreme temperatures. This device is ideally suited

for harsh environments such as wireless remote base stations, automotive/transportation, and industrial

control applications.

It offers enhanced ESD protection and the choice of an MII or RMII interface for maximum flexibility in

MPU selection; all in a 48 pin package.

The DP83848VYB extends the leadership position of the PHYTER? family of devices with a wide

operating temperature range. The TI line of PHYTER transceivers builds on decades of Ethernet expertise

to offer the high performance and flexibility that allows the end user an easy implementation tailored to

meet these application needs.
