/PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced the industry's first 8-channel pulse-width modulator (PWM) audio processor with dual asynchronous sample rate converters (ASRCs) integrated on a single chip. The HD-compatible TAS5548 allows home and pro audio designers to seamlessly mix two audio sources, providing design flexibility and cost savings compared to competitive solutions that require two chips. It accepts sample rates from 8 kHz to 192 kHz and converts them to a fixed rate of 96 kHz or 192 kHz, eliminating the need to create, store and change coefficients. This simplifies the design of digital multi-channel products, such as Blu-ray home-theater-in-a-box (HTiB), A/V receivers, mini/micro combos, and soundbars.

The TAS5548's 40-kHz audio bandwidth is compatible with Dolby
True HD and DTS-HD, and delivers unmatched multi-channel performance. Designers can optimize their products with rich audio processing capabilities, such as 7-band parametric equalization (EQ), bass and treble tone control, volume and loudness control, dynamic range compression (DRC), and input and output mixing.
Key features and benefits of the
Tools and support
- Simplified multi-channel design: Two integrated 4-channel ASRC cores allow audio system designers to switch sample rates without changing coefficients.
- Excellent noise performance: Native processing at 96 kHz for 8-channel output enables ultra-low out-of-band noise and jitter suppression.
- Design flexibility: Extra microphone and I2S input combines with the ASRC's ability to mix two different sample rate sources. This feature provides the flexibility to mix a microphone with up to eight karaoke tracks.
- Efficient power supply design: Integrated smart energy manager delivers more efficient operation. It can limit the audio system's peak power by interrupting the host processor if the power threshold is reached. For high-end audio systems, a power supply volume control enables energy-efficient high-power performance.
- Complete audio solution: Combines with the ultra-low power MSP430™ Value Line microcontroller, PCM9211 digital audio interface transceiver with stereo analog-to-digital converter (ADC), and the TAS5624A and TAS5614LA 150-W stereo/300-W mono PurePath™ HD digital-input power stage devices. Customers can create their high-performance audio systems faster with this complete audio system solution.
