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 GND.
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
When set HIGH in conjunction with SD/HD = HIGH and 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.
When set LOW, the device will be configured to transmit signal rates of
1.485Gb/s or 1.485/1.001Gb/s only.
When set HIGH, the device will be configured to transmit signal rates of
270Mb/s only.
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.
