Description
Power supply connection for the charge pump. Connect to +3.3V
DC analog.
Ground connection for the phase detector. Connect to analog
GND.
Power supply connection for the phase detector. Connect to
+1.8V DC analog.
No connect.
Reserved – connect to analog ground.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
When set HIGH in conjunction with SMPTE_BYPASS = LOW,
the device will be configured to operate in DVB-ASI mode.
When set LOW, the device will not support the encoding of
received DVB-ASI data.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select the input data bus width in SMPTE or
Data-Through modes. This signal is ignored in DVB-ASI mode.
When set HIGH, the parallel input will be 20-bit demultiplexed
data.
When set LOW, the parallel input will be 10-bit multiplexed data.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to enable or disable I/O processing features.
When set HIGH, the following I/O processing features of the
device are enabled:
• EDH Packet Generation and Insertion
• SMPTE 352M Packet Generation and Insertion
• ANC Data Checksum Calculation and Insertion
• TRS Generation and Insertion
• Illegal Code Remapping
To enable a subset of these features, keep IOPROC_EN/DIS
HIGH and disable the individual feature(s) in the
IOPROC_DISABLE register accessible via the host interface.
When set LOW, the I/O processing features of the device are
disabled, regardless of whether the features are enabled in the
IOPROC_DISABLE register.
