DP83848VYB
PHYTER® - Extended Temperature Single Port
10/100 Mb/s Ethernet Physical Layer Transceiver
General Description
The number of applications requiring Ethernet connectivity
continues to increase, driving Ethernet enabled devices into
harsher environments.
The DP83848VYB was designed to meet the challenge of
these new applications with an extended temperature perfor-
mance that goes beyond the typical Industrial temperature
range. The DP83848VYB is a highly reliable, feature rich, ro-
bust device which meets IEEE 802.3u standards over an
EXTENDED temperature range of -40°C to 105°C. This de-
vice is ideally suited for harsh environments such as wireless
remote base stations, automotive/transportation, and indus-
trial 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 LQFP package.
The DP83848VYB extends the leadership position of the
PHYTER family of devices with a wide operating temperature
range. The National Semiconductor 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.
