Here is what the architecture of modern-day dual-speed Ethernet/Wi-Fi router looks like these days. TP-Link’s Archer C7 dual-speed wireless router delivers 1,300 Mbps over the 5 GHz band and 450 Mbps over the 2.4 GHz band. That should be enough bandwidth for HD streaming, online gaming and other bandwidth-intensive tasks. The idea behind using two […]
SMD pulse transformers for Gigabit Ethernet and PoE
TDK Corp. has expanded the ALT4532 series of pulse transformers with new types for Gigabit Ethernet and Power over Ethernet (PoE) applications. The new ALT4532P type is designed for emerging 2.5GBASE-T (2.5 Gbit/sec) and 5GBASE-T (5 Gbit/sec) LAN applications as well as 1000BASE-T (1 Gbit/sec) applications with 600-mA PoE. The new ALT4532H type is compatible […]
LAN transformers come in gigabit versions
The WE-LAN AQ series of LAN transformers are manufactured by full automation and come in a new gigabit package that exhibits outstanding electrical properties and compact design. With WE-LAN AQ, the previous wound toroid cores are replaced with SMD-solderable transformers and common-mode choke elements. The low return loss attenuation gives the package an outstanding signal […]
High-accuracy three-axis magnetometer features low RMS noise and current consumption
A highly accurate three-axis magnetometer combines an extremely sensitive tunnel magneto-resistive (TMR) element developed by TDK and an advanced electronic compass ASIC designed by AKM in a small package. The new TMR magnetometer on a chip, which has miniature dimensions of just 1.6×1.6×0.6 mm, features the industry’s lowest RMS noise of just 40 nT-rms and […]
New 3D image sensor enables easy smartphone unlock by face recognition
A new 3D image sensor in the REAL3 chip family, based on Time-of-Flight (ToF) technology, makes possible the world’s smallest camera module for integration in smartphones with a footprint of less than 12 x 8 mm, including the receiving optics and VCSEL (Vertical-Cavity Surface-Emitting Laser) illumination. Compared to other 3D sensor principles, such as stereoscopic […]
Scalable image-sensor platform for ADAS and autonomous driving aims to speed design, implementation
A scalable family of CMOS image sensors address the spectrum of applications for Advanced Driver Assistance Systems (ADAS) and autonomous driving. Developed by ON Semiconductor, the sensor family offers car makers and tier-one suppliers a choice of imaging devices based on a common platform and feature set. The sensors have resolutions scaling from 8.3 megapixels […]
Teardown: Inside Amazon’s Echo Dot
The Amazon Echo Dot is essentially the top portion of the Amazon Echo, but without the speaker underneath it. Eliminating the big speaker drops the price of the from $180 for the Echo to $50 for the Echo Dot. The Echo Dot does have its own speaker, but the speaker is comparable to what you […]
End-to-end sub-1 GHz kit brings easy cloud connectivity
The element14 development kit for the TI SimpleLink Sub-1 GHz Sensor to Cloud Linux Gateway is based on technology from Texas Instruments (TI). The kit provides an end-to-end tool to enable a Sub-1 GHz sensor network with an Internet of Things (IoT) gateway and cloud connectivity. “Sub-1 GHz offers low-power and long-range wireless connectivity, but […]
DVR records audio/video on microSD storage media in MP4, captures JPEG images on the fly
A/V outputs on the Model 4031 digital video recorder allow live video, recorded A/V or JPEG snapshots to be displayed on an external monitor. Date and time are maintained by a real-time clock with battery backup. Implementation of a complete embedded DVR takes just a power connection, an optional custom keypad, and a microSD storage […]
I2C-programmable XOs provide superior jitter performance for 100/200/400G apps
A new family of high-performance I2C-programmable crystal oscillators (XOs) are said to deliver best-in-class jitter performance and frequency flexibility. With typical jitter performance as low as 95 fsec, the Si544/Si549 Ultra Series programmable XOs maximize jitter margin for clocking high-speed 28 Gbps and 56 Gbps transceivers used in 100/200/400G communications and data center applications. The […]
