Description
Extract Payload
ID (SMPTE
352M)
On, Off
• On: Extract payload ID
• Off: No payload ID extraction (saves logic)
It is compulsory to turn on this option for 3G-
SDI, HD SDI dual link, and triple standard
modes. The extracted payload ID is required for
consistent detection of the 1080p format.
Convert HD-SDI
dual link to 3G-
SDI (level B)
On, Off
• On: Converts to level B (2 × SMPTE 292M
HD-SDI mapping, including SMPTE 372M
dual link mapping) for HD-SDI dual link
receiver output.
• Off: No conversion
This option is only available for HD-SDI dual
link receiver.
Convert 3G-SDI
(level B) to HD-
SDI dual link
On, Off
• On: Converts to HD-SDI dual link (direct
image format mapping) for 3G-SDI receiver
output.
• Off: No conversion
This option is only available for 3G-SDI receiver.
Transmitter
Options
Insert payload ID
(SMPTE 352M)
On, Off
• On: Insert payload ID
• Off: No payload ID insertion (saves logic)

TX PLL type
CMU, ATX
Sets the transmitter PLL type for transmit and
bidirectional ports.
ATX PLL is useful for bidirectional channels—
you can use the ATX PLL as the transmitter PLL
instead of the CMU PLL from another channel.
Dynamic Tx
clocks switching
Off, Tx PLLs
switching, Tx PLL
reference clocks
switching
• Off: Disable dynamic switching
• Tx PLLs switching: Instantiates two PLLs,
each with a reference input clock
• Tx PLL reference clocks switching: Instanti‐
ates a PLL with two reference input clocks.
Turn on this option to allow dynamic switching
between 1 and 1/1.001 data rates.
Note: This option is only available for TX or
bidirectional ports, and all video
standards except SD-SDI.
