Supply Input
8V to 15V supply. A 220F bypass capacitor to GND with a
470nF (ceramic) in parallel is recommended.
826
GATE
External Switch Gate
External MOS switch Gate connection of the step-up converter.

SENSE
Current Sense (Input)
Current Sense comparator input. Connected to current sensing
resistor.
624
VUP
Step-up Voltage
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.

VORX
Output Port during
22KHz Tone RX
RX Output to the LNB in DiSEqC 2.0 application. See truth table
for voltage selections and description on page 4.

DSQIN
DiSEqC Input
When the TEN bit of the System Register is LOW, this pin will
accept the DiSEqC code from the main
controller. Each section
of the LNBH221 will use this code to modulate the internally
generated 22kHz carrier. Set to GND this pin if not used.
422
DETIN
Detector In
22kHz Tone Detector Input. Must be AC coupled to the DiSEqC
bus.
