Edinburgh, United Kingdom, May 2013 -Wolfson Microelectronics, a leading global mixed-signal semiconductor solution design and development company in the consumer electronics market, has announced the launch of a highly flexible high-definition audio hub (HD) with product code WM8997 Audio Hub), which has synchronous SLIMbus® and I2S interfaces designed for cost-effective solutions to provide excellent high-definition audio for smartphones and other portable devices.
The WM8997 high-performance HD audio hub provides an excellent signal-to-noise ratio (SNR) of 102dB, while the playback power consumption from the digital-to-analog converter (DAC) to the headset is only 6.5mW, enabling clear and crisp voice calls, and excellent The tone of audio recording and music playback. Its synchronous SLIMbus® and I2S interface capabilities provide original equipment manufacturers (OEMs) with platform architecture flexibility, can support independent audio digital signal processors (DSPs), and ensure that the same audio solution can be reused on any platform There is no need to consider the audio interface; this saves development costs and time, and provides easy-to-integrate, non-obsolete solutions.
The WM8997 digital core combines fixed-function signal processing units including filters, equalizers, dynamic processors, and sample rate converters with a fully flexible, all-digital audio mixing and routing engine to provide excellent application scenarios flexibility. It also supports voice and gesture control, and the use of digital pens. WM8997 supports up to 4 microphone inputs, each microphone can be analog or pulse density modulation (PDM) digital.
