SiFive has announced RISC-V core intellectual property for data centre processors. Called P870-D, it is an update of the non-data centre P870, with support added for AMBA CHI protocol. “By harnessing a standard CHI bus,” said SiFive, “the P870-D enables SiFive’s customers to scale up to 256 cores while harnessing industry-standard protocols including CXL [Compute Express Link] and CHI C2C [chip ...
The Optical Transport market is forecasted to grow 2 percent on average for the next five years due to a decline in 2024 caused by customers pausing purchases to digest excess inventory, says Dell’Oro Group. “2024 is turning out to be a tough year for the Optical Transport equipment market because of inventory digestion,” said says Dell’Oro vp Jimmy Yu, ...
Renesas is aiming at wireline infrastructure and data centres with a family of 25fs rms jitter 25fs-rms clock generators and jitter attenuators with eight or 12 outputs. RC32312 and RC32308 “provide phase noise and jitter required to meet the needs of 112Gbit/s as well as 224Gbit/s SerDes designs using commonly-available 48MHz to 73MHz crystals”, claimed the company. “The devices can ...
A family of clock generators shifts the focus of SiTime from oscillators. The Chorus family is the second announcement from the company, following its introduction of clock generators in 2020. Oscillators make up 95% of the company’s revenue, explained Piyush Sevalia, SiTime’s executive vice president of marketing, but the acquisition of Indian’s Aura Semiconductor brought its clock products and clock ...
ITG Electronics is aiming at server motherboards and storage devices with a series of high-current surface-mount ferrite inductors. The SLA36385A series has a 5 x 9mm footprint and 9.5mm height, and yet the components can handle up to 230A. Inductances range across 35 to 470nH. “The 35nH component can handle more than 200A, with approximately 20% roll off”, said the ...
Siemens EDA has announced three products, for emulation, evaluation and software prototyping for data centres and servers. The Veloce CS consists of the Strato CS hardware, for emulation, the Primo CS hardware for enterprise prototyping and proFPGA CS hardware for software prototyping. According to the company, the hardware-assisted verification and validation system can accelerate verification and validation cycles by up ...
Google has announced a $1 billion investment in a new UK data centre, sited in Waltham Cross, Hertfordshire. The 33-acre site “will bring crucial compute capacity to businesses across the UK” says Google, “supporting AI innovation and helping to ensure reliable digital services to Google Cloud customers and Google users in the UK and abroad”. It will “create construction and ...
To meet Open Compute Project (OCP) requirements, Molex has created a connector system that combines low-speed signals, high-speed signals and power into a single cable assembly. The “data-center product development team collaborated with the power engineering group to optimise power-contact design, thermal simulation and power dissipation”, according to the company. Inside is up to 4A can be carried alongside 10 ...
At Semicon Taiwan, Navitas Semiconductor announced GaNSafe, its fourth generation GaN technology. It is designed in a TOLL package to be rugged and protected in demanding environments and suitable for commercial applications in data centres, inverters in solar panels and onboard chargers in electric vehicles. The choice of a TOLL reduces the size compared to a QFN, explained Stephen Oliver, ...
Navitas is claiming it can deliver 3,200W from a 40 x 73.5 x 185mm (544cm3) data centre power supply, which is 5.9W/cm3 and almost 100W/in3. Called CRPS185, it has a 1U CRPS (common redundant power supply) form-factor. Inside, the architecture starts with an interleaved CCM (continuous conduction mode) PFC (power factor corrector) and continues into a full-bridge LLC (inductor-inductor-capacitor) converter ...
