TYPICAL APPLICATION CIRCUITS
Application Circuit for DiSEqC 1.x and Output Current < 450 mA
Full Application Circuit for Bi-directional DiSEqC 2.0 and Output Current up to 750mA
(*) Filter to be used according to EUTELSAT recommendation to implement the DiSEqC
TM
2.0, (see DiSEqC
TM
implementation on page 8).
If bidirectional DiSEqC
TM
2.0 is not implemented it can be removed both with C8 and D4.
(**) Do not leave these pins floating if not used.
(***) To be soldered as close as possible to relative pins.
-C8 and D3,4 are needed only to protect the output pins from any negative voltage spikes during high speed voltage transitions.
