Kyoto Semiconductor Co., Ltd. Launches New Photodiode Demonstrating Superior Performance With Semtech’s Linear Transimpedance Amplifier
Kyoto Semiconductor Co., Ltd. (President and CEO Tsuneo Takahashi, Head office: Fushimi-ku, Kyoto city), a leading optical device solution manufacturer with world-class technologies and Japanese quality, announced its collaboration with Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms. Kyoto Semiconductor has chosen to pair their new KP-A avalanche photodiode*1, KPDEA13C with Semtech’s GN1089 transimpedance amplifier*2 to enable long distance optical communication.
"The pairing of Semtech’s transimpedance amplifier GN1089 with Kyoto Semiconductor’s KPDEA13C was ideal to optimize the performance,” said Tsuneo Takahashi, Kyoto Semiconductor president and CEO. “Through the joint collaboration, the KPDEA13C now includes a fast response suitable for a variety of optical needs.”
Kyoto Semiconductor’s KPDEA13C is front side illuminated, highly sensitive and mounted on an interposer board for ease of assembly. Additionally, Kyoto Semiconductor’s KPDEA13C and Semtech’s GN1089 together offer unparalleled performance at high speed enabling 25Gbaud PAM4*3*4 applications.
"Semtech’s GN1089 is a high performance transimpedance amplifier enabling both 25Gbaud and 56Gbaud applications. Its high linearity and low noise are features that were a perfect fit for the Kyoto Semiconductor, KPDEA13C,” said Timothy Vang, vice president, marketing and applications for Semtech’s Signal Integrity Products Group. “This collaboration with Kyoto Semiconductor showcases the outstanding quality of our solutions for high speed optical communications.”
Sample shipments of KP-A avalanche photodiode, KPDEA13C is scheduled to begin on August 31, 2021, and mass production is expected to start on December 27, 2021.

*1 Avalanche Photodiode: Semiconductor Photodiode with photocurrent amplification by applying reverse bias voltage. This photocurrent amplification produces much more current than standard Photodiode. It is useful in the application where the high sensitivity is required.
*2 Transimpedance amplifier: The circuit or device that convert a current from Photodiode to voltage.
*3 PAM4 (Pulse Amplitude Modulation 4-level): A technique of modulation. It uses four voltage levels to represent two bits logic, 00, 01, 10, and 11, against the traditional NRZ modulation uses two voltage levels to represents 1 bit logic, 0 and 1.
*4 25Gbaud PAM4: PAM4 signal at 25Gbaud modulation speed. It achieves 2 times transmission speed compared with traditional 25Gbaud NRZ signal. i.e., 25Gbaud PAM4 achieves 50Gbps, against 25Gbaud NRZ achieves 25Gbps.

Ferring Pharmaceuticals to Explore Strategic Options for Rebyota ®29.10.2025 15:00:00 EET | Press release
As part of our ongoing transformation to sharpen our focus, we have decided to explore strategic options for Rebyota® (faecal microbiota, live – jslm). To date, more than five thousand patients suffering from recurrent Clostridioides difficile infection (rCDI) have found new hope when treated with Rebyota®. Without commercial critical mass in this therapy area at Ferring, we believe that this first-in-class, innovative product could benefit many more patients with a new approach to its continued commercialisation. As a result, Ferring will reduce commercial efforts in the United States while ensuring uninterrupted access for patients. Approved by the U.S. Food and Drug Administration (FDA) in 2022, Rebyota® was the first FDA-approved faecal microbiota transplant, indicated for the prevention of rCDI in adults following antibiotic treatment for recurrent CDI. This milestone marked a significant advancement in understanding the role of the human microbiome in health and disease. Ferring

375ai Launches Data Layer for the Physical World on Solana29.10.2025 15:00:00 EET | Press release
375ai, an edge data intelligence company transforming the physical world into structured, machine-readable insights, today announced the launch of its mainnet on Solana. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20251028976994/en/ 375ai Launches Data Layer for the Physical World The physical world is generating more data than ever before, but most of it is invisible. Traffic systems, advertising platforms, and governments still rely on outdated infrastructure and fragmented data sources to understand how people and goods move through cities. Centralized data pipelines are expensive, slow, and often limited to incomplete or delayed insights. Meanwhile, AI systems are hungry for real world context not just synthetic inputs. Without structured, real time data, they can’t power smarter mobility, logistics, and safety solutions. 375ai enables real world data capture, unlocking a new category of physical AI infrastructure.
