8 to 15 V IC DC-DC power supply.
8 to 15 V analog power supply.
Integrated N-Channel power MOSFETs drain.
Input of the linear post-regulators. The voltage on these pins is
monitored by the internal step-up controllers to keep a
minimum dropout across the linear pass transistors.
Outputs of the linear post-regulators. See
selections and description.
TX Outputs to the LNB. See
Bi-directional data from / to I²C BUS.
Clock from I²C BUS.
These pins will accept the DiSEqC code from the main
microcontroller. The LNBH24 will uses this code to modulate
the internally-generated 22 kHz carrier. Set to ground if not
used.
