Electrostatic discharge occurs when electronic components are improperly handled and can result in intermittent
failure or complete damage adversely affecting an electrical circuit. When you remove and replace any card from
a frame always follow ESD-prevention procedures:
Ensure that the frame is electrically connected to earth ground through the power cord or any other means if
available.
Wear an ESD wrist strap ensuring that it makes good skin contact. Connect the grounding clip to an
unpainted surface of the chassis frame to safely ground unwanted ESD voltages. If no wrist strap is available,
ground yourself by touching the unpainted metal part of the chassis.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohms.
When temporarily storing a card make sure it is placed in an ESD bag.
Cards in an earth grounded metal frame or casing do not require any special ESD protection.

1 Introduction to the XIP-3901 Agile SDI/IP Processing Platform
The Densité 3+ XIP-3901 from Grass Valley, a Belden Brand, is a new agile processing platform that focuses on
high-quality live production for HD, 1080p, 4K UHD and HDR. This platform is a bridge for the hybrid world,
consisting of today’s proven SDI technology and the latest IP connectivity.
Figure 1  Densité 3+ and XIP-3901
To meet customers’ needs both now and in the future, the XIP-3901 uses a flexible “virtualized” hardware
platform. Based on a powerful FPGA engine, the XIP-3901 can be reconfigured with software updates for different
applications as requirements change.

XIP-3901 -UC / -DC / -FS SDI Applications
The applications for the XIP˗3901 agile IP/SDI processing platform provides full functionality of up/down/frame
sync-gearbox processing capability delivered through three applications that allow your live productions —either
from trucks, venues or stadiums —to make the most of the new 4K UHD and HDR formats. This includes playout
channels where output of a 4K UHD HDR channel needs to be downconverted for an HD SDR simulcast version.
The XIP-3901 agile processing platform with the rear panel XIP-3901-3+DRP-H comes with all the 12G/Quad Link
3G/3G/HD HD-BNC SDI connectivity to support two 4K UHD processing paths with the XIP-3901-UC/DC/FS
applications. The rear panel XIP-3901-3+DRP is also available for DIN SDI connectivity for backward
compatibility, but Grass Valley is now promoting the HD-BNC as the miniature SDI connector going forward. The
XIP-3901 is installed in a Densité modular frame. Due to advanced processing capabilities and power
requirements, the XIP-3901 is supported only by the Densité 3+ FR1 and FR4 frames.
Densité 3+ XIP-3901-UC is an application that provides a dual-channel 12G/Quad Link 3G/3G/HD-SDI
upconverter, which is designed to synchronize, upconvert and process HD and 3G 1080p signals for both 1080p
and 4K UHD 2160p broadcast production. The XIP-3901-UC application features broadcast-quality scalers,
motion-adaptive de-interlacers and color space conversions between ITU-R BT.709 and ITU-R BT.2020.
Densité 3+ XIP-3901-DC is an application that provides a dual-channel 12G/Quad Link 3G/3G/HD downconverter,
which is designed to synchronize, downconvert and process 4K UHD 2160p and 1080p for both 1080p and HD
broadcast production. The XIP-3901-DC application features broadcast-quality down-scalers, interlacers and
color space conversions between ITU-R BT.2020 and ITU-R BT.709.
Densité 3+ XIP-3901-FS is an application that provides a dual-channel 12G/Quad Link 3G/3G/HD frame
synchronizer with gearbox functionality, which is designed to synchronize and convert color space between ITU-R
BT.2020 and ITU-R BT.709 in 4K UHD, 1080p and HD broadcast productions.
All applications will delay 12G/3G/HD embedded audio and metadata to maintain synchronization with video. The
optional HDR processor, XIP-3901-UDC-HDR, allows conversion between SDR and HDR formats, supporting
HLG (ITU-R BT.2100), PQ (ITU-R BT.2100) and S-Log3/S-Gamut3 formats, with conversion between formats. In
addition to the Grass Valley LUTs, you can select BBC LUTs v1.4 or you can choose your own Custom LUTs
compliant to Adobe cube file v1.0 for fully flexible HDR processing.
Based on the proven Densité modular framework of over 100 cards, the flexible, space-efficient XIP-3901 agile
processing platform can accommodate a gradual adoption of different production elements into 1080p and 4K
UHD broadcasting workflows —and it enables dual HDR/SDR production —all while protecting your investment
in installed equipment. With flexibility to configure up to 12 XIP-3901 dual-channel processing applications per
Densité 3+ FR4 frame, the Densité platform scales to a market-leading density of 24 4K UHD processors with
HDR conversions in a 4 RU frame. This means space and cost-efficient scaling for today and tomorrow.

XIP-3901-GB-IP Application
The XIP-3901-GB-IP is a dual-channel 4K UHD gearbox application for conversion between Quadstream 1080p
Two Sample Interleave (2SI) or Square Division Quad Stream (SDQS) and Single-stream 4K UHD supporting IP
with dual 25 GbE I/O. Based on open standards, this IP edge gearbox processing application is compliant to the
SMPTE ST 2110 suite of standards and JT-NM TR-1001 technical recommendation for easy integration in a
broadcast IP network production environment.
The XIP-3901-GB-IP solves 4K UHD production problems with early IP devices implementing Quad-stream
1080p and SMPTE ST 2110-20 recommendations for Single-stream 2160p, which can be a gap when building a
complete end-to-end 4K UHD solution.
The XIP-3901-GB-IP also supports four streams of SMPTE ST 2110-30/31 audio conforming to Level A and Level
C, as well as one stream of SMPTE ST 2110-40 metadata per channel of IP gearbox.
The XIP-3901-GB-IP is configured, controlled and monitored by GV Orbit, taking advantage of its many features
and functions specifically crafted to make IP easy. It can also be configured and controlled from iControl systems.
Based on the proven Densité modular framework with over 80 card types, the flexible, space-efficient XIP-3901
agile processing platform can accommodate a gradual adoption of different production elements into 1080p and
4K UHD broadcasting workflows, all while protecting your investment in installed equipment. With flexibility to
configure up to 12 XIP-3901 dual-channel processing applications per Densité 3+ FR4 frame, the Densité
platform scales to a density of 24 4K UHD processors in a 4 RU frame. This means space and cost-efficient
scaling today and tomorrow.
All the processing applications delivered on the XIP-3901 platform allow live productions, either from trucks,
venues, stadiums or broadcast facilities to make the most of new UHD and HDR formats. Packing lots of
audio/video processing power in a small form factor means considerable savings in terms of space, power and
weight.
