DP83220  
CDLTM Twisted Pair FDDI Transceiver Device  
General Description  
Features  
Y
Fully compatible with current FDDI PHY standard  
The Copper Data Link (CDL) Transceiver is an integrated  
circuit designed to interface directly with the National Semi-  
conductor FDDI Chip Set or other FDDI PHY silicon, allow-  
ing low cost FDDI compatible data links over copper based  
media. The DP83220 Transceiver, with the proper compen-  
sation selected, will allow links of up to 100 meters over  
both Shielded Twisted Pair (STP) and Datagrade unshielded  
Y
Fully compatible with the SDDI PMD specification

signed to meet the SDDI specification for FDDI transmission  
across Type 1 STP cable when used in conjunction with the  
appropriate transformer/filter module from Pulse Engineer-  
ing.
