Gennum Fall 2011 Product Guide • Broadcast Video
Product Spotlight
We’ve leveraged our extensive history and expertise in the broadcast video industry to design and build the industry’s
first 290x290 fully non-blocking asynchronous switch—the flagship solution in our new family of crosspoints. These are
not parts adapted from the data communications market. They were designed for broadcast video from the ground up.
Our years in the broadcast industry have given us a unique understanding of the video market. That’s why we have built
in industry-first features like eight strobe enable pins, which enable the crosspoint to be “broken up” into 8 smaller
crosspoints. This gives system designers the flexibility to design for multi-format applications or for re-configuring only
one part of the switch where necessary.

Crosspoint Switches
Video-specific Features Developed from the ‘Ground Up’
for SDI (SD, HD, & 3G), 3D, and Ultra HD
Gennum crosspoint switches provide an unmatched
combination of size, features and performance. At sizes
up to 290 inputs and 290 outputs, these are the largest
asynchronous, fully non-blocking crosspoint switches in
the industry.
Designed for Broadcast
Gennum’s history in the broadcast market has given us
a thorough understanding of the nuances of broadcast
equipment, allowing us to design specifically for these
applications. Using this expertise, we introduced several
features that are new to the industry such as multiple
strobe enable pins, the industry’s greatest input and output
flexibility and a pattern checker that supports arbitrary
patterns. All of these features make our crosspoints easy to
use, while providing superior performance.
Multiple StrobeS
Eight update enable strobe pins allow the crosspoint
to be broken into smaller pieces, each of which can be
independently updated. Independent updates also allows for
more deterministic control by allowing parallel operations
to occur vs. serializing multiple time domain events. This is
useful in multi-format environments when the switches will
occur at different points in time. Because each update strobe
can be assigned on a per-output basis, this feature enables
maximum flexibility.
Data rate margin
Supporting data rates up to 3.5Gb/s means that there is
significant margin for systems operating up to 2.97Gb/s. The
3.5Gb/s data rate support also means that the product can be
used in Xaui™, DisplayPort™ and HDMI applications.

On-chip Pattern Generators and Checkers
With two independent pattern generators and pattern
checkers on chip, the GX3290 (and family) can be used for
testing and diagnosing system channel issues on either the
input or output side of the system. Support for PRBS 7, 15,
and 23 patterns in the generator means that there is enough
flexibility to evaluate the system under different stress
conditions. The pattern checker can check one of the three
PRBS patterns above or it can be configured to check bit
errors on any arbitrary pattern. This is particularly useful
for evaluating system performance with stressful video
pathological signals.

Fully independent input and output channels
All of Gennum’s crosspoint products provide independent
input trace equalization and output de-emphasis, which
can compensate for over 50 inches of PCB trace loss. This
industry leading trace equalization allows customers the
flexibility to utilize long traces and/or passive splitting of
signals in their designs with more confidence in overall
signal integrity and lower jitter. Also, the wide input
sensitivity (80-1200mV) means that output amplitudes from
upstream chips can be reduced, saving overall system power.
In addition, each output can be independently powered
down for greater flexibility. With output wings as low as
200mV, system power can be significantly reduced when the
crosspoint is followed closely by another device.
By offering both serial and parallel host interfaces with
normal and auto-increment modes, you can choose the
interface and mode of operation that works best in your
system. This makes it easy to interface to a variety of control
devices, from FPGA and microcontroller based architectures.
Eye Pattern Diagnostics
The GX3290 can check for bit errors at arbitrary phase offsets
from the received data. This allows you to measure jitter
margin using horizontal eye opening values.
Gennum Fall 2011 Product Guide • Broadcast Video
Crosspoint Switches
Industry’s largest crosspoint switch, designed specifically for broadcast
Temperature sensors
Input Sensitivity
Four on-chip temperature sensors monitor the junction
temperature of the chip and provide this information via
registers, where the system can read them. This allows the
user facilitates automated control of fan speed and power
down sequences that prevent the chip and system from
overheating.
The GX3290 family of crosspoints feature industry
leading input sensitivity. High input sensitivity provides
additional system margin to address losses typical in
many architectures attributable to long board traces, series
connectors and passive splits. In addition, high input
sensitivity facilitates better system optimization, including
reduced swing on upstream drivers, providing substantial
power savings.
Dynamic Output power down and signal invert
Having the output power down and signal invert functions
tied to the strobe enable pins guarantees that outputs enter
or exit power down mode when other switches tied to the
same strobe are occuring in the matrix. This combination
of dynamic output power down and high input sensitivity
enables passive expansion using multiple crosspoint devices,
eliminating the need for hundreds of costly and powerhungry splitter and combiner components.
Industry’s Largest switch product
Gennum’s new family of crosspoint devices includes the
industry’s first 290x290 crosspoint switch. Even when the
core switch requirements are less than a full 290x290, extra
I/O can be used to provide additional opportunities for
differentiation. For example, the I/O could be used as a
loop back with auxiliary processing for signal reporting,
monitoring and jitter cleaning.
Low Power
As the broadcast industry evolves to support video formats
such as 3D and UltraHD, the need to support multiple
data rates and video formats will dramatically increase the
size and complexity of next-generation broadcast video
systems. Gennum’s crosspoint portfolio not only delivers the
superior size, performance and power management required
by these systems, but gives equipment manufacturers
and broadcasters alike the ability to monitor and control
performance.
Even with higher output swing voltages, Gennum is able to
achieve less than 40W for 290 active channels. Per channel
power consumption is industry leading when compared to
competitive solutions and is also highly scalable with less
than 1W power consumption in stand-by mode. System
power can be further reduced by taking advantage of the
crosspoint’s high input sensitivity and using Gennum’s
GS2993/94 and GS3440/41 equalizers at minimum output
swing levels.
Applications
Flexible Footprint
Routers, multiviewers, production switchers, master
control switchers and next generation, connected modular
equipment.
The GX3290, 3190, 3246, 3202, and 3146 are all pin
compatible. Also, sharing the same interface and register
set, one design can be easily scaled to the necessary switch
size with no rework required in either hardware or software,
allowing multiple end products to be launched from one
common platform.

Reclockers
Industry’s lowest power and lowest jitter 3Gb/s solutions
Improved Jitter Tolerance
Additional FEATURES
As routers and distribution systems grow in size, system jitter
increases. Reclocking has become important in maintaining
overall system robustness. In addition, as processing is being
integrated into more and more devices, reducing the overall
jitter in a system is critical given that many processing
specific devices like FPGAs can have poor IJT. Performance
leading reclockers such as the Gennum GS2985 can be
utilized to increase overall system margin.
The GS2965, GS2985, and GS2986 add input trace
equalization and output signal de-emphasis, which provides
additional flexibility to system designers. In addition, the
serial control interface to these devices provide multiple
communication methods. These devices also feature
automatic slew rate control when used with Gennum’s cable
drivers for multiformat applications.
The integrated 2:1 or 4:1 signal selection mux at the input
of the Gennum reclockers allows them to be utilized in
architectures that require switching matrices and failover
redundancy. This reduces the need for additional signal path
components and their associated jitter.
MULTI-RATE
Gennum reclockers offer robust multi-standard operation
from 270Mb/s to 2970Mb/s and are SMPTE 424M, 292M and
259M-C compliant.

3 video clocks (2 single-ended and one differential), 3 singleended audio clocks, and 8 single-ended configurable timing
signals can be generated. Video clocks up to 165MHz can be
produced in order to support up to 3Gb/s SDI and UXGA.
In addition, the GS4911B features crosslocking capability
where HD timing can be generated from an SD reference,
increasing design flexibility.
SD (27MHz), and HD (74.25, 74.25/1.001, 148.5,
148.5/1.001MHz) frequencies can be input and output from
the GS4915. The chip also has single-ended and differential
inputs and outputs to facilitate interfacing with a variety of
chips.
INPUT STANDARD DETECTION
If the input clock frequency is 74.25 or 74.25/1.001MHz, the
GS4915 can double the output, providing a low jitter 148.5 or
148.5/1.001MHz output clock which can be used for HD-SDI
and 3Gb/s SDI applications.
FREQUENCY DOUBLER TO MEET 3Gb/s SDI
REQUIREMENTS
By supplying the clock generator with HSync, VSync and
Fsync, the chip will determine if it matches one of 36 video or
16 graphics standards and will report the detected standard.

As a designer, you have the choice of selecting components
from different vendors. But when it comes to designs with
serializers and deserializers, you first have to choose an
architecture. In implementing a design with a serializer
and/or deserializer, you have 3 architectural choices at your
disposal: Gennum’s complete serializer/deserializer solution
architecture, an integrated-transceiver FPGA architecture
and an FPGA-helper architecture. Let’s explore these three
options with an assessment of the following key parameters:
jitter, power consumption, integration (component/features),
time-to-market, system size and cost.

Leveraging our expertise in signal integrity and our deep
understanding of broadcast video technologies, Gennum’s
SDI serializer and deserializer offering encapsulates all
the analog components (SerDes, VCO, CD, EQ, Reclocker)
and digital SMPTE video and audio processing required
to transmit and receive SDI video. This optimized, costeffective and power efficient ASIC implementation that lets
you focus on your value-added processing for quicker timeto-market. All of this integration into one package reduces
the PCB footprint required to implement SDI transmit/

What is CWDM? Why do I need it?
The third generation family of products offers robust, single
point-to-point links for a single datastream per fiber. To
send another signal, one could add another fiber link, but
this is not always desirable or feasible. Since optical fiber has
such a large bandwidth, it is possible to combine multiple
signals and send them down a single fiber. This is known as
multiplexing.
Signal 1
Signal 2
Signal 3
Signal 4
Signal 1
Optical DeMUX
While the use of optical technology within the broadcast
studio is increasing, not all solutions provide the same level
of robustness, performance and reliability. For over 20 years
Gennum has been bringing industry leading, innovative
solutions and support to the broadcast market. This
leadership also extends to the optical space where Gennum
has been bringing innovative optical products to the
datacom and telecom industries for over ten years. Gennum’s
Video SFP Optical modules are at the intersection of
Gennum’s excellence in both video and optical technologies.
With our third generation Video SFP Optical modules now
shipping in volume, we are expanding our module portfolio
by launching a new CWDM family of products.
Optical MUX
As the building of 3Gb/s SDI capable infrastructure
continues, there has been a sharp increase in the use of
fiber optic interfaces for the transport and distribution
of 3Gb/s SDI signals due to the declining implementation
costs. At these higher data rates, fiber optic systems
provide a number of advantages vs coax cables including
virtually unlimited capacity and transmission distance and
immunity from electromagnetic interference. Optical fiber
is also significantly smaller and lighter than coax allowing
smaller and lighter cable harnesses, which can be a huge
benefit where space and weight is tightly constrained as in a
production truck.
Signal 2
Signal 3
Signal 4
With CWDM (Coarse Wavelength Division Multiplexing),
multiple lasers tuned to specific wavelengths are grouped
together with optical filters (Optical MUX) and travel
independently along a single fiber. At the end of the fiber,
filters are used to separate (Optical DeMUX) the individual
wavelengths. CWDM uses wavelengths separated by 20nm
beginning at 1271nm to 1611nm. A total of 18 wavelengths
are available to combine on a single fiber. The lasers used
in CWDM transmitters also have a higher power and much
narrower spectral width resulting in signals traveling much
longer distances, up to 50 km in a 3Gb/s CWDM installation.
Gennum’s video SFP Optical modules are engineered to
provide industry leading optical performance and robustness
for mission-critical broadcast applications. The module
family is growing, as can be seen in the next few pages.
Expect many more additions to the family moving forward.
Leveraging years of technical experience in both the
broadcast and optical markets, Gennum’s Video SFP Optical
modules are engineered to provide industry leading optical
performance.

Video Optical Modules
Extend the reach of 3Gb/s-SDI over optical fiber
Robust Performance
Video or Datacom Pinout Option
Not all video optical modules are created equal. Gennum’s
optical modules are built upon Gennum’s excellence in both
SDI and optical technology. Incorporating custom receiver
silicon, Gennum Rx modules feature an exceptional dynamic
range ensuring maximum interoperability with SMPTE 297
compliant transmitters. Additionally, Gennum’s modules
provide robust performance across all operating conditions,
ensuring a highly reliable optical link.
Gennum is pleased to offer both video and datacom pinout
variants for all new products. This allows network equipment
manufacturers to add optical SDI interfaces to any existing
products that were designed around the SFP MSA pinout.
Third Generation Products
Gennum’s third generation video SFP optical modules
demonstrate Gennum’s ongoing commitment to supply the
broadcast market with the most robust video SFP solutions.
The latest modules provide exceptional value in short reach
optical applications and offer design improvements and
enhanced functionality.
Gennum’s third generation SFPs offer an improved mechanical
design with a superior latching and delatching mechanism.
Additionally, all the new modules feature a user writable
EEPROM that allows equipment manufacturers to program
their own information within the SFP to enable their
equipment to identify qualified modules.
COMPACT, PLUGGABLE, FLEXIBLE
Gennum’s small form factor modules for digital video (Video
SFP) are hot pluggable, easy to use, and offer the highest
density optical solution for carrying digital video over optical
fiber. The Video SFP pinout is designed so that one slot can
be populated with a dual transmitter, dual receiver, single
transmitter, single receiver, or a transceiver.
MULTI-RATE AND BACKWARD COMPATIBLE
Gennum’s Video SFPs operate from 50Mb/s to 3Gb/s and
seamlessly run at 3G-SDI, HD SDI and SD SDI rates without
any system level intervention required to change the data rate.
They can also be used for other formats such as Ethernet and
SONET.
MONITORING AND CONTROL
All of Gennum’s Video SFPs are equipped with an I2C interface
for monitoring and control of key parameters such as module
temperature, optical power and bias current.

PCI Express Video Solution
®
The easiest way to transport SDI video over PCI Express
COMPLETE PCI EXPRESS SOLUTION
REFERENCE DESIGN KIT AVAILABLE
Gennum provides a complete solution for video capture over
PCI Express including the GN4124 PCI Express-to-local bus
bridge, SDI serializers/deserializers, software, and firmware.
A complete RDK for video capture is available.
PCI EXPRESS CABLE EXTENSION SOLUTION
Gennum PCIe re-driver solutions provide new alternatives
for system partitioning and extension. The GN1407 quad
PCIe re-driver, and the GN1406 quad retiming re-driver,
allow PCI Express to be extended across long cables.
GN4124 PCI EXPRESS BRIDGE
The GN4124 is designed to work as a companion to FPGA
devices to provide a complete bridging solution. Since the
PCI Express transaction/link IP is hard-wired into the
GN4124, there is no need to license PCIe IP. Using the
GN4124 allows FPGA resources to be spent on differentiating
features.
PCIe Re-driver and Retiming Re-driver
The GN1406 provides high-gain equalization (up to 24dB) for
PCI Express for Gen1/Gen2 data rates to compensate for
cable losses. Standard PCI Express cable or lower cost
alternatives may be used. The GN1406 is unique in that
also provides retiming in order to achieve the longest
cable lengths and address impairments such as crosstalk,
source jitter, interpair skew, and reflections that cannot be
compensated for by equalization alone. By resetting the jitter
budget through retiming, the GN1406 provides the greatest
robustness and lowest jitter solution available. Each of the 4
channels in the GN1406 includes independently adjustable
input equalization and output de-emphasis.
Live on Power-up
The GN4124 devices are live on power-up so that a plug-andplay BIOS can auto-detect them without an attached FPGA
having to be configured.
FPGA On-the-Fly Configuration Loader
An FPGA configuration bitstream may be downloaded from
the host system over PCIe to the attached FPGA.
Local Bus Interface
GN1407 is similar to GN1406, except that it does not have
the retiming and output de-emphasis features.
The local bus interface uses dual data rate to achieve up to
800MB/s of local bus peak throughput in each direction
(1600MB/s total peak throughput).
A complete reference design kit, including schematics and
board layout, is available from Gennum.
FIRMWARE/SOFTWARE
The Gennum video capture solution includes FPGA firmware
and driver software provided at no extra cost when used with
the GN4124.
