TI introduces highly integrated audio codec to speed soundbar development

Texas Instruments » PCM3070

Value Soundbar Reference Design Kit based on PCM3070 reduces total solution cost by 30 percent compared to discrete implementations

Texas Instruments Incorporated introduced a flexible stereo audio codec with two fully-programmable miniDSP cores to support customized processing solutions for use in soundbars and docking stations. The PCM3070 includes a stereo 24-bit digital-to-analog converter (DAC), stereo 24-bit analog-to-digital converter (ADC) and integrated phased-locked loop (PLL) for flexible audio clock generation. The codec enables designers to produce high-quality, low-cost soundbar solutions and, coupled with the Value Soundbar Reference Design Kit, develop their products quickly.
