NOTES:
4. Internal digital soft-start.
5. VO1 for LNB1, VO2 for LNB2. Voltage programming signals VSEL1, VSEL2, LLC1, and LLC2 are implemented via the I
2
C bus.
IO1 = IO2 = 350mA/750mA.
6. Guaranteed by design.
7. Unused DSQIN 1&2 pins should be connected to GND. SEL18V1&2 pins have 200K internal pulldown resistors.
