Input
Serial output disable. When asserted LOW, the SDO/SDO output driver
is powered off. SDO/SDO will float to V_CC through the pull-up resistor.
Power Most positive power supply connection. Connect to +3.3V.
Input
Output slew rate control. When set HIGH, the output will meet ST 259
rise/fall time specifications (270Mb/s operation). When set LOW, the
serial outputs will meet HDcctv 1.0/ST 292 (1.485Gb/s data rate) and ST
424 (2.970Gb/s data rate) rise/fall time specifications .
Output Serial digital differential output.
Power
Connect to most negative power supply plane following the
recommendations in Recommended PCB Footprint on
page 11.
