Stereo audio codec

20 July 2011 Analogue, Mixed Signal, LSI

Texas Instruments has introduced a flexible stereo audio codec with two fully programmable miniDSP cores to support customised 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 32-bit miniDSP engines enable implementation of branded audio effects, multiband dynamic range compression, and custom filters and algorithms.The SRS WOW HD feature, included as a standard feature, improves the playback quality of audio, delivering a dynamic 3D entertainment experience with rich bass and high-frequency clarity for crisp detail.

The PCM3070 is a core component of TI’s Value Soundbar reference design kit. This integrated solution is optimised to deliver 30% lower cost than a discrete solution, and helps designers get to market in approximately eight weeks. In addition to the PCM3070, the open-tool reference design board includes TI’s DIR9001 digital audio receiver, PCM2705 USB DAC, TPA3110D2 Class-D amplifier and MSP430F2131 low-power microcontroller. The kit includes the board, schematics, gerber files, bill of materials, user manual and software.
