Power supply for the Phase Detector 1.8V DC
CONTROL SIGNAL INPUT
Signal levels are LVCMOS / LVTTL compatible.
When set HIGH, the device will be configured for the transmission
of DVB-ASI data in SDTV mode, (SD/HD must be HIGH and
SMPTE_BYPASS must be LOW).
When set LOW, the device will not support the encoding of DVB-
ASI data.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS / LVTTL compatible.
Used to select the current video rate as either 1.484 Gb/s HDTV or
270Mb/s SDTV. When SD/HD is HIGH, the mode is 270Mb/s.
The setting of this pin also determines the parallel input / output
clock rate and the slew rate of the cable driver output.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS / LVTTL compatible.
Used to select the input bus width in SMPTE or Data-Through
modes.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS / LVTTL compatible.
Used to enable or disable I/O processing features
When IOPROC_EN/DIS is HIGH, the following I/O processing
features of the device are enabled.
•
•
•
•
•
•
To enable a subset of these features keep IOPROC_EN/DIS HIGH
and disable features in the host iterface.
When IOPROC_EN/DIS is LOW, the I/O processing features of the
device are disabled, regardless of whether the features are
enabled in the host interface.
