Description
Control signal input.
When set HIGH, the serial data output will meet the SMPTE 259M rise/fall time
specification.
When set LOW, the serial output will meet the SMPTE 292M and SMPTE 424M rise/fall
time specification.
NOTE: if this pin is left floating, the serial data output will meet the SMPTE 259M
rise/fall time specification.
Serial data differential output.
Output signal presence status signal output.
Signal levels are LVCMOS/LVTTL compatible.
Indicates presence of a valid output signal.
When the OSP pin is LOW, a good input signal has been detected within the output
stage pre-driver.
When this pin is HIGH, the output signal is invalid at the output of the pre-driver.
Control signal input.
When set LOW, trace-equalization is turned ON.
When set HIGH, trace-equalization is turned OFF.
NOTE 1: if this pin is left floating, trace-equalization is turned OFF.
NOTE 2: this pin must be pulled HIGH or left floating for operation in SD mode.
Connect to most negative power supply plane following the recommendations in
Recommended PCB Footprint on page 15.
