8 to 15 V analog power supply.
8 to 15 V IC DC-DC power supply.
Integrated N-Channel power MOSFET drain.
Input of the linear post-regulator. The voltage on this pin is
monitored by the internal step-up controller to keep a
minimum dropout across the linear pass transistor.
Output of the integrated low drop linear post-regulator. See
truth tables for voltage selections and description.
TX Output to the LNB. See truth tables for selection.
Bi-directional data from/to I²C bus.
Clock from I²C bus.
This pin will accept the DiSEqC code from the main
microcontroller. The LNBH23 will use this code to modulate
the internally generated 22 kHz carrier. Set to ground if not
used.
This pin can be used, as well as the TTX I²C bit of the system
register, to control the TTX function enable before to start the
22 kHz tone transmission. Set floating or to GND if not used.
22 kHz tone decoder Input, must be AC coupled to the
DiSEqC 2.0 bus.
