TDK Launches Noise Suppression Filters for Audio Lines of High Sound Quality Devices

TDK Corporation has announced its latest compact noise suppression filters MAF1005FR series, measuring 1mm (L) x 0.5mm (W) x 0.5mm (H). These multilayer chip components are designed to improve sound quality and reduce noise interference in the audio lines (sound lines) of smartphones, portable devices, and wearables. Mass production of the new EMC components series started in November 2023.

CEVA announced that its RivieraWaves Bluetooth Dual Mode 5.3 Platform has achieved Bluetooth SIG Qualification, along with its GAF (Generic Audio Framework) and LC3 codec. As the first IP company to receive Bluetooth Dual Mode 5.3 qualification, CEVA brings the latest improvements in Bluetooth connectivity and LE Audio to the market, lowering the entry barriers for semiconductors and OEMs targeting LE Audio applications. 1 billion CEVA-powered Bluetooth devices are estimated to have shipped in 2021.

With the audio market increasingly using digital data interfaces for the most demanding applications, Wireworld Cable Technology, one of the world's most respected brands of high performance audio and video cables, announced the release of their second generation Ethernet patch cables. The new “Series 8” patented flat design uses higher density triple-layer shields and quieter Composilex 3 insulation to maximize audible and visible performance.

Saelig has introduced the Alldaq ADQ-USB 3.0-ISO series of USB 3.0 isolators, which support the full USB 3.0 SuperSpeed data rate of 5Gbit/s. This allows USB 3.0 SuperSpeed devices to be electrically isolated from a host PC or other peripherals at full performance. The USB 3.0 SuperSpeed Isolator eliminates ground loops and ground potential differences and is ideal for measurement, industrial, automotive and audio technology applications.

When we connect audio components, interference may occur from various power and signal grounds. This circuit enables the full galvanic isolation of sound frequency signals with optical transmission in excellent quality, eliminating interference.
