For low-noise operation, the LXT385 ransceiver is designed so that each transmitter has its own
power and its own ground. These pins are not necessarily internally connected. For example, for
channel 0 transmit, TGND0 is the corresponding ground pin and TVCC0 is the corresponding
power pin.

Ground (Core) 1:0.
GND0 and GND1 pins are ground for the digital core.
Ground (I/O) 1:0.
GNDIO0and GNDIO1 pins are grounds for the digital I/O
interface.
Transmit Driver Ground 7:0.
TGND[7:0] pins are grounds for the output drivers. Must
be tied to PC board ground at all times.
Transmit Driver Power Supply 7:0.
TVCC[7:0] pins are the power supply pins for the
corresponding output drivers.
