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: G

Integrated-transceiver
FPGAs typically offer
the worst
specifications
in terms of jitter. Maximum output jitter and input
j
i
tt
e
r
tolerance (IJT) are
typically
at the limit of the
SMPTE
standards, and, in some
cases, actually
in violation of industry
n
o
r
m
s
.
Th
a
t
is why extra components, namely a
VCXO
and
reclockers,
are required to get the system jitter performance to an acceptable
level,
but at the penalty of higher power consumption, system footprint
size
and cost.
Because
of all the fine tuning required
t
o
g
e
t
this
architecture to work, and because of the IP licensing/development required for the digital
SMPTE
video processing,
t
h
is
architecture unnecessarily prolongs time-to-market.
Finally,
while
FPGAs
integrate transceivers, they do not integrate
r
o
u
t
i
n
g
components like cable drivers and equalizers.

The FPGA-helper architecture, as depicted
below, involves
the use of a component that includes the
physical
media
a
tt
a
c
h
me
nt
p
a
r
t
of a
SMPTE
receiver/transmitter, with the digital
SMPTE
processing implemented in the
FPGA.
The result is an
a
r
c
h
i
t
ec
t
u
r
e
that is
taxing in terms of power consumption and that FPGA-helper parts are
lacking,
in terms of feature
offering.
In many cases,
customer code already requires high utilization factors in small, low-cost
FPGAs
and the added requirement of digital SMPTE
video processing in the FPGA may drive adoption of a larger
FPGA,
creating further penalties in power consumption,
size
a
n
d
system cost. And while this architecture fares
well
in system jitter performance in certain
cases,
the added engineering effort
i
n
developing (or licensing) and stitching that video processing
logic
with the customer code means a slower time-to-market. Finally,
while some FPGA-helper parts integrate a cable driver, the
offering lacks
an integrated equalizer.

The heart of the Gennum PCI
Express
video solution is
t
h
e
GN4124,
a 4-lane PCI
Express-to-local
bus bridge. Unlike
legacy
bridge solutions (PCIe to PCI bridges), the GN4124
takes full advantage of the performance features of PCIe.
The
GN4124
is designed to work as a companion to FPGA
devices
to provide a complete bridging solution. The GN4124
contains a PCI
Express
compliant PHY and the link
a
n
d
transaction
layers,
and an applications interface.

Since
the PCI
Express
transaction/link IP is
h
a
r
d-
wi
r
e
d
into the
GN4124,
there is no need to
license
PCIe IP. Using
the
GN4124 allows

The

are
live
on power-up so that a

BIOS
can auto-detect them without an attached FPGA
having to be configured.

An FPGA configuration bitstream may be downloaded

the host system over PCIe to the attached
FPGA.
This
eliminates the expense of a dedicated FPGA ROM and makes
on-the-fly reconfiguration and firmware upgrades simple.
Any application requiring dynamic reconfiguration

benefit from the use of the
GN4124
as a companion device.
The local bus interface uses dual data rate to accomplish
up
to
800MB/s
of local bus peak throughput in each
