The following diagram shows a typical block diagram
for a twin universal LNB design. The ZLNB2006/09/10
group of devices provides the two polarity and two
Additionally the front end bias requirements of the LNB
are provided by ZNBG4000 or ZNBG6000 offering a
very efficient and cost effective solution
tone switches required to decode the two independent
receiver feeds. The ZLNB2009/10 devices are also able
to detect the absence of receiver 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.
