DECEMBER 11, 2009 -- Nanotech Semiconductor Ltd., a fabless IC company specializing in advanced CMOS analog and mixed-signal ICs for fiber-optic communications, has released the NT24L55, a high-sensitivity, low-power, pure CMOS 1.25-Gbps transimpedance amplifier (TIA) targeting the latest generation of GEPON networks.
The NT24L55 builds on Nanotech's portfolio of CMOS TIAs for datacom, telecom, and FTTH networks and is the first in a new family of pure CMOS ICs designed to provide high performance at the lowest power consumption.
The TIA can achieve typical sensitivities better than -32 dBm at a bit-error rate (BER) of 10-12 with a standard 0.5-pF Gigabit PIN photodiode, while consuming 30-mA supply current. Typical bandwidth in this configuration is 1 GHz and the IC supports a large range of photodiode types, offering customers flexibility in terms of optical assembly.
Nanotech says this latest TIA has the most flexible bond pad configuration available. Compatible with all major TO-can layouts, the NT24L55 features left- or right-side power supply pads, a data polarity invert function, and photodiode current mirror that is selectable to sink or source output type.
Engineering Samples are available now. Purchase orders for mass-production will be accepted from January for delivery starting March 2010.
"Our latest TIA delivers best in class performance and is the first product in a line of new pure CMOS ICs for the fiber access market demonstrating Nanotech’s commitment to deliver innovative, world-beating products," says Gary Steele, chief executive officer.
Adds Christian Rookes, marketing manager for glass fiber products, "The NT24L55 will enable our customers to deliver the highest-sensitivity receiver products with the lowest power consumption for fiber access networks and take advantage of the capacity, availability, and reliability that pure CMOS fabrication offers."
