Inphi Corporation Introduces High-Speed, Low-Noise Transimpedance Amplifiers for OC-768 Applications.Business Editors NOTE TO MEDIA: Photo is available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com and at www.newstream.com WESTLAKE VILLAGE, Calif.--(BUSINESS WIRE)--March 18, 2002 New Line of 40, 43, and 50 Gbps Amplifiers Enables OEMs to Design High-Bandwidth Optical Receivers for Multiple Market Segments Inphi Corporation, a privately held fabless optical components company, today announced the introduction of three high-gain transimpedance amplifiers (TIAs) for integration into SONET OC-768 and SDH (Synchronous Digital Hierarchy) The European counterpart to SONET. See SONET. SDH - Synchronous Digital Hierarchy STM-256 optical receivers. Fabricated in indium phosphide phosphide Any of a class of chemical compounds in which phosphorous is combined with a metal. Phosphides exhibit a wide variety of chemical and physical properties. Phosphides that are rich in metal have high melting points and are hard, brittle, and chemically inert; these , the 4330TA, 4332TA, and 5030TA achieve network transmission speeds of 40 gigabits per second (Gbps) and higher at extremely low power levels. All three TIAs are optimized for use with positive-intrinsic-negative (PIN) photodetectors and are capable of amplifying input currents ranging from 40 microamps peak-to-peak to 3 milliamps peak-to-peak while maintaining a bit error rate (BER (1) (Basic Encoding Rules) A set of encoding rules for ASN.1 notation, which is a method for defining data structures. See ASN.1. (2) (Bit Error Rate) The average number of bits transmitted in error. See BERT. 1. ) of 10(-12). These amplifiers enable OEMs to customize their receiver modules for a variety of optical network applications. "These high-performance amplifiers round out Inphi's mux, demux, and driver product lines and enable us to offer a complete solution for 40G systems," said Kevin Nary nar·y adj. Not one: "Frequently, measures of major import . . . glide through these chambers with nary a whisper of debate" George B. Merry. , Vice President of Engineering at Inphi. "The combination of high gain, high bandwidth, and excellent input sensitivity will enable OEMs to reduce design costs and at the same time offer their customers a robust receiver module for next-generation networks." 4330TA and 4332TA Designed for short-reach, intermediate, and long haul networks, the 4330TA and 4332TA operate at data rates up to 44 Gbps for non-return-to-zero (NRZ (Non-Return-to-Zero) A data transmission method in which the 0s and 1s are represented by different polarities, typically positive for 0 and negative for 1. See NRZI. NRZ - Non Return to Zero ) transmission formats. The 4330TA has a differential electrical gain of 2000 Ohms, eliminating the need for additional external amplification between the TIA (1) (Telecommunications Industry Association, Arlington, VA, www.tiaonline.org) A membership organization founded in 1988 that sets telecommunications standards worldwide. It was originally an EIA working group that was spun off and merged with the U.S. and the demultiplexer and optimizing it for use with most demultiplexers available today. For applications that use optical amplification and hence have a lower TIA gain requirement, the 4332TA with its 1200 Ohms of differential gain is an ideal solution. The 4330TA and 4332TA have a bandwidth of 40 GHz (see Figure 1), which is sufficient to support NRZ applications up to 43 Gbps. At the same time, the input sensitivities of these amplifiers can achieve BERs of less than 10(-12) for input current amplitudes as low as 40 microamps peak-to-peak. The outputs of both amplifiers support differential as well as single-ended operation, and the output zero-crossing point is adjustable via a DC offset control pin. 5030TA The 5030TA is intended for ultra long haul systems and high-end applications requiring super forward error correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it. (SFEC SFEC Super Forward Error Correction (Sycamore) SFEC Source Coding Based Forward Error Correction ). The 5030TA operates at data rates up to 50 Gbps with sufficient bandwidth to support both return-to-zero (RZ) and NRZ transmission. This amplifier has a bandwidth of 55 GHz and a linear input dynamic range of 200 microamps peak-to-peak to 3 milliamps peak-to-peak, making it a good fit for RZ applications up to 50 Gbps. The outputs of the 5030TA also support both differential and single-ended operation, and the output zero-crossing point is adjustable via a DC offset control pin. The 4330TA, 4332TA, and 5030TA each dissipate less than 350 milliwatts of power and operate off a single +3.3 volt power supply. They are available in die form (830 x 980 micrometers) for integration into small form factor, low-power receiver modules. All three TIAs are currently sampling to Tier 1 customers and are available for immediate purchase.
