Description
7*
DISABLE2
Input
Control signal input.
When set LOW, the second serial digital output is disabled (powered-down) and the
SDO2/SDO2 pins are set to high-impedance.
When set HIGH, the SDO2/SDO2 pins will output a serial digital signal.
NOTE: if this pin is left floating, the second serial digital output will be disabled.

Output
Output
Serial digital differential output of second output buffer.

SDO1/
SDO1
Serial digital differential output of first output buffer.

NC
–
No connect. Not internally bonded.
Control signal input.

SD/HD
Input
When set HIGH, the serial digital outputs will meet the SMPTE 259M rise/fall time
specification.
When set LOW, the serial outputs will meet the SMPTE 292M rise/fall time
specification.
NOTE: if this pin is left floating, the serial digital outputs will meet the SMPTE 259M
rise/fall time specification.

Center Pad
Power
Connect to most negative power supply plane following the recommendations in
Recommended PCB Footprint on page 13.
*NOTE: When pins 6 and 7 are driven LOW together (or similarly when pin 6 is driven LOW while pin 7 is left floating), the
entire device is powered-down. In this state, bare minimum power consumption occurs.
