Nanotech Semiconductor Limited (search for Nanotech
Semiconductor), a fabless IC company specializing in
advanced Analog & Mixed-Signal ICs for fiber-based
communications applications, today announced what it claims
is a breakthrough in CMOS transimpedance amplifier (TIA)
design. |

Nanotech's new family of 2.5-Gbit and
10-Gbit TIAs offers at least 3-4 dB more sensitivity at each
data rate vs. the best existing devices, which are typically
in expensive SiGe processes, say company representatives.
The NT25L55 offers -33 dBm typically at 2.5 Gbits/sec, with
a standard PIN diode, and with only 33-mA current
consumption. The NT25L55 can therefore be used to replace
APD-based devices in GPON networks, offering dramatic cost
and power savings, contends Nanotech.
The NT28L50 and NT28L51 offer -25 dBm typically at 10 Gbits/sec,
again with only 33-mA consumption. The NT28L50 is intended
for upcoming SFP+ modules, while the NT28L51 is tailored to
LRM applications. Nanotech believes that both ICs offer not
only the highest performance in the world, but are also the
world's first CMOS 10-Gbit/sec TIAs.
All ICs require a single 3.3-V supply and are pin-compatible
with previous products. On-chip filtering means no
capacitors are required inside the ROSA, offering both
bill-of-materials (BOM) cost reduction and faster, lower
cost assembly, says the company. Photodiode monitor
source/sink and output polarity are both bond-programmable,
offering complete build flexibility.
Alpha customers are being sought now, with production
ramp-up expected early in 2008.
"Manufactured in standard 0.13-[micron] CMOS, at the world's
largest wafer foundry, this new family of ICs offers
customers exactly what they need in terms of reliability,
short manufacturing lead-times, and CMOS pricing, in
addition to the best performance ever seen," asserts Dr. Ya
Nong Ning, Nanotech's marketing director for GOF products.
"One of the most interesting things about this latest
architectural breakthrough is that it builds upon the
company's earlier solutions to the challenges in the Plastic
Optical Fiber (POF) world," adds CEO Gary Steele. "Not only
does this new architecture offer both higher sensitivity and
lower power, but it is also extremely forgiving of its opto-electrical
and mechanical environment, something the consumer- and
auto-orientated POF world takes for granted, but that is
relatively new to the glass fiber world. " |
