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: if this pin is left floating, trace-equalization is turned OFF.
Connect to most negative power supply plane following the recommendations in
