Silicon Laboratories have unveiled the industry’s first crystal-less USB-to-I2S audio bridge designed to support a wide range of codecs and digital-to-analog converters used in USB-based audio applications. The new CP2114 audio bridge chip simplifies the process of transferring audio data from USB to I2S without time-consuming code development, speeding time to market for USB audio accessories such as speakers, headphones, music boxes, point-of...

TI have unveiled the industry's first serial digital interface reclocker with an integrated eye monitor for examining the shape and health of incoming signal waveforms. The on-chip eye monitor provides real-time monitoring and diagnostics at the reclocker's input, allowing engineers to easily optimize their broadcast video system and speed time-to-market.

Communications infrastructure, imaging equipment, industrial instrumentation, defence electronics and other multi-channel, data-hungry systems are demanding wider resolutions and higher sampling rates from the data conversion stage. Physical layout constraints of the parallel interface and bit-rate limitations of the serial low-voltage differential signalling approach are beginning to present technical barriers for designers.
