Partners collaborate on DOCSIS 4.0 chipset
Comcast and Broadcom are working together to develop a DOCSIS 4.0 chipset that embeds AI and ML capabilities to create AI-powered access networks. The chipset will be one of the first to incorporate DOCSIS 4.0 Full Duplex (FDX), Extended Spectrum…
Event-based vision sensor caters to edge AI
Prophesee has launched the GenX320, an event-based Metavision sensor architected for integration into ultra-low-power edge AI vision devices. Offered in a tiny 3×4-mm die size, the back-side illuminated (BSI) stacked sensor provides a 320×320…
Signal-conditioner ICs join PCIe 5.0 ecosystem
PCIe 5.0 retimers and redrivers from Phison provide signal enhancement for PCIe-deployed devices like NAND flash, FPGA, ASIC, and other accelerator technologies. They are part of Phison’s portfolio of PCIe 5.0 storage and signal conditioning…
DOCSIS 4.0 chipset targets modems and gateways
Puma 8 is MaxLinear’s DOCSIS 4.0 cable modem and gateway chipset supporting frequency division duplex (FDD), also known as Extended Spectrum (ESD). The chipset comprises a DOCSIS SoC, AnyWAN SoC, and a low-power, ultra-high split upstream…
How Arm Total Design is built around 5 key building blocks
The ecosystem has been Arm’s key strength and is evident from its latest initiative: Arm Total Design. After unveiling the Neoverse Compute Subsystems (CSS)—high-end cores for infrastructure applications like AI, cloud, data center, and…
Frequency divider from 1 to 4096 in increments of 1
Frequency dividers are usually realized on ICs and have a fixed and small division coefficient. In this article, a frequency divider is proposed that allows you to set the frequency division coefficient of a digital signal from 1 to 4096 in…
Electromechanical relays: an old-fashioned component solves modern problems
One of the frustrating challenges in integrating systems is interfacing an existing subsystem with a new or different subsystem. In cases where the input/output characteristics of both sides are standard and known, a level-shifter/translator…
Checking out a USB microphone
I’ve been covering microphones and their accessories a fair bit lately, so I thought it’d be fun to take one apart and see what’s inside. Not just any old mic with an XLR, TRS or other analog output, mind you; I also wanted my dissection…
The story of NI and its influence on instrument control
National Instruments, widely known as NI in the test and instrumentation worlds, will become the Test & Measurement unit in Emerson after the completion of the $8.2 billion acquisition. The St. Louis, Missouri-based industrial conglomerate…
Adjust op-amp gain from -30 dB to +60 dB with one linear pot
A good manually adjusted audio gain stage is characterized by:
Low noise and low distortion,
A 20 kHz bandwidth,
A wide gain adjustment range (e.g. 90dB), and
Logarithmic (at least pseudo-logarithmic) control characteristic to
Efficiently span…
Bidirectional I/O for communicating power mode between ECUs
In recent days, the number of electronic control units (ECUs) in the car continues to increase, at the same time there is a necessity to reduce the sleep current to improve the efficiency of the battery. In gas powered cars this has become mandatory.
Wow…
32-bit MCUs embed hardware-based security
Microchip’s PIC32CZ CA series of 32-bit MCUs integrates a hardware security module (HSM) for applications that require secure communications. Powered by a 300-MHz Arm Cortex-M7 processor, the microcontrollers also offer a wide range of connectivity…
