10-Bit Bus LVDS Serializers
The serializers can operate in a variety of topologies.
Examples of double-terminated point-to-point, mul-
tidrop, point-to-point broadcast, and multipoint topolo-
gies are shown in Figures 11 through 14. Use 1%
surface-mount termination resistors.
A point-to-point connection terminated at each end in
the characteristic impedance of the cable or PCB
traces is shown in Figure 11. The total load seen by the
serializer is 50Ω. The double termination typically

reduces reflections compared to a single 100Ω termi-
nation. A single 100Ω termination at the deserializer
input is feasible and will make the differential signal
swing larger.
A serializer located at one end of a backplane bus dri-
ving multiple deserializers in a multidrop configuration
is shown in Figure 12. A 54Ω resistor at the far end ter-
minates the bus. This topology allows “broadcast” of
data with a minimum of interconnect.
