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 integrated low drop linear regulators. See
Table 7
Tone outputs to the LNB. See
Bidirectional data from / to I²C bus.
Clock from I²C bus.
These pins will accept the DiSEqC code from the main
microcontroller. The LNBH24L will uses this code to modulate
the internally generated 22 kHz carrier. Set to ground if not
used.
These pins can be used, as well as the TTX I²C bits 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.
To be connected to GND.
To be connected to the external NPN transistors base to
reduce the 22 kHz tone distortion in case of heavy capacitive
load at light output current. If not used they can be left floating.
