CABLE EXTENDER APPLICATION
The DS15BA101 together with the DS15EA101 form a cable
extender chipset optimized for extending serial data streams
from serializer/deserializer (SerDes) pairs and field pro-
grammable gate arrays (FPGAs) over 100Ω differential (i.e.
CAT5e/6/7 and twinax) and 50Ω coaxial cables. Setting cor-
rect DS15BA101 output amplitude and proper cable termina-
tion are keys for optimal operation. The following two figures
show recommended chipset configuration for 100Ω differen-
tial and 50Ω coaxial cables.
