LVDS
Depending on whether the device is transmitting an LVDS
signal or receiving an LVDS signal, there are two different
circuits used for LVDS termination. A sample circuit illustrat-
ing a valid termination technique for transmitting LVDS sig-
nals appears in
Figure 54
. A sample circuit illustrating a
valid termination for receiving LVDS signals appears in
Figure 55
.
Table 38
lists DC voltage specifications. Further
information on the specific termination resistor packs shown
can be found on
Table 40
.
LVPECL
Depending on whether the device is transmitting or receiv-
ing an LVPECL signal, two different circuits are used for
LVPECL termination. A sample circuit illustrating a valid ter-
mination technique for transmitting LVPECL signals
appears in
Figure 56
. A sample circuit illustrating a valid ter-
mination for receiving LVPECL signals appears in
Figure 57
.
Table 39
lists DC voltage specifications. Further
information on the specific termination resistor packs shown
can be found on
Table 40
