Input /
Output
CONTROL SIGNAL INPUT / STATUS SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
This pin will be an input set by the application layer in slave mode, and will
be an output set by the device in master mode.
Master Mode (MASTER/SLAVE = HIGH)
The SMPTE_BYPASS signal will be HIGH only when the device has locked
to a SMPTE compliant data stream. It will be LOW otherwise.
Slave Mode (MASTER/SLAVE = LOW)
When set HIGH in conjunction with DVB_ASI = LOW, the device will be
configured to operate in SMPTE mode. All I/O processing features may be
enabled in this mode.
When set LOW, the device will not support the descrambling, decoding or
word alignment of received SMPTE data. No I/O processing features will
be available.

Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to enable or disable the serial digital output loop-through stage.
When set LOW, the serial digital output signals SDO and SDO are
disabled and become high impedance.
When set HIGH, the serial digital output signals SDO and SDO are
enabled.

Power
Ground connection for the serial digital cable driver. Connect to analog

Output
Serial digital loop-through output signal operating at 1.485Gb/s,
1.485/1.001Gb/s, or 270Mb/s.
The slew rate of these outputs is automatically controlled to meet SMPTE
292M and 259M specifications according to the setting of the SD/HD pin.
