Semtech Delivers Industry's First Solution for Transporting up to Eight HDTV SDI Signals
Across a Single 12G SDI Link

AMSTERDAM, Netherlands, Sept. 08, 2016
(GLOBE NEWSWIRE)
-- Semtech Corporation (Nasdaq:SMTC), a leading
supplier of analog and mixed-signal semiconductors, will demonstrate eight 1.5G serial digital interface (SDI) signals
transported across a single 12G SDI coaxial cable link utilizing its GS12070 Gearbox at the International Broadcasting
Convention (IBC) exhibition, stand 10.F46, on September 9-13 in Amsterdam.

The ability to transport up to eight 1.5G HDTV SDI signals across a
single 12G link adds additional capabilities to facilities with 12G SDI
infrastructures by simplifying the routing and distribution of multiple
1.5G HDTV signals. Rather than utilizing up to eight discreet coaxial
links, 12G link concatenation exploits the massive bandwidth available
in a single 12G link to transport up to eight 1.5G SDI signals.
The 12G concatenated link conforms to The Society of Motion Picture
and Television Engineers' (SMPTE) proposed ST 2082-30 12G SDI
link concatenation standard. Link concatenation utilizing SMPTE's
proposed standard can significantly reduce infrastructure complexity
and cost without additional risk of interoperability issues in a facility
that supports multiple data rates, including 1.5G, 3G, 6G, and 12G
SDI.
The demonstration utilizes Semtech's GS12070 Gearbox. The GS12070 is the industry's only single chip SDI link
concatenation and rate conversion solution that enables equipment manufacturers and broadcasters to take a standards-
based, commercial, off-the-shelf approach to deploying UHDTV infrastructures.
"Link concatenation is a necessary requirement for any broadcast facility installing new 12G infrastructures," said Don
Shaver, Director of Video Marketing for Semtech's Signal Integrity Product Group. "Beyond the inherent efficiency of
transporting multiple signals across a single 12G SDI link, the ability to do so while providing seamless interoperability in a
fully standards-based environment is a critical requirement for any new facility."
Key Features of the GS12070
l Link Concatenation: Supports SMPTE's proposed ST2082-30 12G link concatenation standard facilitating multiple
1.5G, 3G, 6G SDI signals across a single 12G link.
l Fully integrated gearbox solution: Four-input and four-output ASIC supporting conversions between multi-link,
dual-link and single-
link UHD
-SDI interfaces.
l Automatic skew correction: For multi-link inputs, automatic compensation for channel skew—an unavoidable
system challenge in multi-
link UHD
-
SDI systems
—that exceeds the SMPTE's recommended skew tolerance
specification. This minimizes the need for additional system resources and simplifies the overall system design.
l Integrated 4x4 crosspoint switch: Enables signal routing by selecting from any of the four 12G UHD-SDI inputs to
any of the four 12G UHD-SDI outputs making it an ideal choice for UHDTV routing and distribution applications. In
addition, any of the active outputs can be copied to unused outputs.
l Automatic link ordering: Automatic link ordering for multi-link interfaces simplifies integration and automatically
compensates for UHD-SDI cabling issues that often arise during installation.
