DP83848C PHYTER
- Commercial Temperature
Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver
General Description
The DP83848C is a robust fully featured 10/100 single
port Physical Layer device offering low power con-
sumption, including several intelligent power down
states. These low power modes increase overall prod-
uct reliability due to decreased power dissipation. Sup-
porting multiple intelligent power modes allows the
application to use the absolute minimum amount of
power needed for operation.
The DP83848C includes a 25MHz clock out. This
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 DP83848C easily interfaces to twisted pair media
via an external transformer. Both MII and RMII are
supported ensuring ease and flexibility of design.
The DP83848C features integrated sublayers to sup-
port both 10BASE-T and 100BASE-TX Ethernet proto-
cols, which ensures compatibility and interoperability
with all other standards based Ethernet solutions.
The DP83848C is offered in a small form factor (48 pin
LQFP) so that a minimum of board space is needed.
