The following diagram shows a typical block diagram
for a twin universal LNB design. The ZLNB2013 device
provides the two polarity and two tone
required to decode the two independent receiver feeds.
The device is also able to detect the absence of a
revceiver connection to either port of the LNB
providing all outputs to go high hence disabling of the
port. This allows the avoidance of unwanted signal
reflections from an unterminated down feed cable.
