For high-speed parallel backplanes,
GTLP is the answer.
Migrate to next-generation speed
In today's interconnected, bandwidth-
hungry world, designers can easily
increase by two to three times the data
throughput speed of their networking,
communications and telecommunica-
tions systems by migrating to TI's new
GTL-Plus (GTLP) logic family for parallel
backplanes. And since GTLP is back-
wardly compatible with traditional logic
such as ABT, ALVT, LVT, LVC and
FutureBus+, the migration to higher
throughput is simple and direct.
Building upon its pioneering work
with Gunning Transceiver Logic (GTL),
TI has optimized the Output Edge
Control
TM
circuitry and added live
insertion and removal capabilities to
produce devices specifically designed
for medium and heavily loaded parallel
backplanes.
GTLP brings the benefits of GTL –
higher frequencies and lower EMI and
transmission noise - to parallel back-
planes in excess of 20 slots. Combining
Output Edge Control circuitry with
GTLP's narrow signal voltage swing
gives GTLP clock speeds in excess of 80
MHz and data throughput rates of at
least 3.2 gigabytes per second (Gbps)
across a 32-bit backplane.
Users of the Internet, wireless com-
munications or the traditional wireline
infrastructure are clamoring for more
bandwidth. As a result, the parallel
backplanes used in switches, routers,
hubs and other communications
equipment is quickly evolving to faster
speeds. GTLP logic is an easy first
step toward higher data throughput.
