1.3 Sideband Interface
1.3.1 General Information
The sideband interfaces provide a bi-directional data path subdivided into several logical data streams with different
bandwidth in both directions:
Downstream: Data direction from Transmitter (INDT) -->
Upstream: Data direction to Transmitter (INDT) <--
to Receiver (INDR)
from Receiver (INDR)
Activating the upstream sideband data transmission necessitates an additional pair of wires to establish the physical uplink
(see 1.1 Link Interface). STP cables usually contain 4 pairs of wires; thus this extra connection is available in most cases.
If the upstream sideband data channel is not used, it has to be disabled. The downstream sideband data channels can be
partially disabled to provide extra bandwidth for the pixel data transmission.
