Description
The GS12070 is a highly configurable UHD-SDI Gearbox
which performs multiplexing and de-multiplexing
necessary to facilitate conversions between SMPTE ST
425-3 and/or ST 425-5 (multi-link 3G-SDI) Interface and
SMPTE ST 2081-1 (6G UHD-SDI) and/or ST 2082-1 (12G
UHD-SDI) Interfaces. The Gearbox also supports conversion
between 4 x HD-SDI and 6Gb/s SDI.

Example of Multiplexing ST 425-5 into ST 2081-1 (6Gb/s) and
ST 2082-1 (12Gb/s)
For the supported SMPTE conversions, the SMPTE ST 352
payload identification will be automatically detected and
replaced based on the user selected conversion mode. This
can be bypassed for proprietary multiplexing and
demultiplexing links.
The device incorporates the ability to reorder the output
serial stream and duplicate outputs to unused output
channels or route any input channel.
The GS12070 has the ability to automatically compensate
for up to 400ns of skew between QL 6Gb/s or DL 12Gb/s
inputs and 800ns of skew between DL 6Gb/s and QL 3Gb/s
inputs. This aids in any lane-to-lane variance introduced by
cable mismatch or upstream routing and distribution
equipment.
