Serial digital differential input.
Most negative power supply connection. Connect to GND.
External output amplitude control resistor.
No Connect. Not bonded internally.
Serial output disable. When asserted LOW, the SDO/SDO output driver is
powered off. SDO/SDO will float to VCC through the pull-up resistor.
Do not connect.
Most positive power supply connection. Connect to +3.3V.
Serial digital differential output.
Connect to most negative power supply plane following the
recommendations in Recommended PCB Footprint on page 12.
