WESTLAKE VILLAGE, Calif. -- Expanding its product portfolio for the high-performance telecommunications and data communications markets, Inphi Corporation ( today announced the 1348TA and 1349TA Integrated Linear Transimpedance Amplifier with Automatic Gain Control. These TIAs operate at data rates up to 11.3 Gbps, and can amplify input currents over the entire dynamic range required by the upcoming IEEE 10GBASE-LRM standard, with extremely low – less than 5% – total harmonic distortion (THD). This preserves the input data characteristics and allows an electronic dispersion compensation (EDC) circuit in the receiver to easily recover data from a distorted signal.

These parts are essential for optical receivers used in 1310 nm multi-mode fiber links employing EDC engines that recover signals distorted by multi-path propagation. The primary application is for 10 Gbps Ethernet as defined by the 10GBASE-LRM (long reach over multimode fiber) specification. The 1348TA is intended for TO-can receivers while the 1349TA targets butterfly receivers. The 1348TA and 1349TA are the only linear TIAs available that leverage through-wafer via (TWV) technology. This unique feature simplifies the internal package assembly by eliminating ground bond wires and reducing the number of bypass caps. More importantly, TWVs enhance optical receiver performance by maintaining a flat gain versus frequency profile, increasing the output return loss and decreasing cross talk and jitter.

“Inphi continues to drive the industry’s price/performance standards for TIA in the optical market,” said Kevin Nary, vice president of engineering at Inphi Corporation. “Our close relationship with customers ensures that devices like the 1348TA and 1349TA meet the challenges they face in design, performance and manufacturability. With Inphi’s wide array of complementary building blocks, optical module designers can create better performing solutions at competitive prices, and bring them to market quickly.”

“LRM-based optical modules are poised to enable mass deployment of 10 Gigabit Ethernet in the enterprise backbone,” said Babak Nabili, director of marketing at Scintera Networks, Inc. “Availability of linear TIAs is a key element to enable the implementation of these cost-effective modules.”
