ASICs with integrated
multi-gigabit transceivers, Plug & Play Signal
Integrity lets you change the position of
backplane cards on the fly while eliminating the
painstaking process of manually reconfiguring
your backplane equalization settings
With this capability, you can design systems
with truly universal cards that plug into
multiple card positions in system backplanes (as
shown in this picture in the right. Altera’s
hot-socketable transceivers, coupled with
adaptive dispersion compensation engine
(ADCE) technology, deliver Plug & Play Signal
Integrity where the same card configuration can
be used, irrespective of slot position in most
systems.
In our 28-nm Stratix V FPGAs, the adaptive
engine extends beyond linear equalization.
When operating high-speed serial links in noisy
environments, the benefits of the 5-tap decision
feedback equalization (DFE) mitigates the
effects of cross-talk to ensure high reliability of a
system with a low bit-error ratio (BER).
Plug & Play Signal Integrity offers wide-ranging
benefits:
• Reduced card-type inventories
• Increased system flexibility
• Reduced maintenance and training costs
• Simplified order code management
• Reduced effort in the lab, since you no
longer need to characterize every card slot
to determine the optimal signal integrity
setting for each one.
When you design with Altera, you can design
with the confidence that variations (in
manufacturing, materials, temperature, voltage,
and silicon process) are continuously monitored
and compensated for by the ADCE to deliver the
best eye opening and system BER performance.
