  1. Fujitsu Microelectronics offers paper on 56-GSa/s analog -to -digital converter

    MAY 27, 2010 -- Fujitsu Microelectronics America, Inc. has released a technical paper entitled, "The Fujitsu 56GSa/s Analog-to-Digital Converter Enables 100GbE Transport." The paper describes the technology challenges involved in creating a long-haul 100-Gbps optical transport network and the enabling technology developed by Fujitsu for 100-Gbps Ethernet and OTU-4 transport systems using coherent receivers. The paper also describes the forces Fujitsu Microelectronics believes are pushing towards a single-chip CMOS approach for a 100-Gbps coherent receiver with four 56G-Sa/s analog-to-digital converters (ADCs) and a tera-OPS DSP that dissipates tens of watts. The paper concludes with details on Fujitsu's CHArge-mode Interleaved Sampler technology (CHAIS), which the company asserts enables the implementation of extremely fast, high-resolution ADCs in CMOS process technology (see "Fujitsu launches ADC technology for 100G" . The paper is available on Fujitsu’s website here . Visit Fujitsu Microelectronics America
