D2-926xx 数字频子系统.pdf

Intelligent Digital Amplifier and Sound Processor D2-926xx The D2-926xx family of the DAE-3? and DAE-3HT? Digital Audio Engine? devices are complete System-on Chip (SoC) multi-channel digital sound processors and Class-D amplifier controllers. The integrated DSP provides efficient and configurable audio signal path processing including equalization, dynamic range compression, mixing, and filtering that is completely configurable via the Audio Canvas? III high level programming interface. The integrated PWM engine supports programmable and dynamic control of audio output, enabling a variety of multi-channel output configurations and output power capacity. Internal noise shaping, an embedded asynchronous sample rate converter, dynamic level-dependent timing, and high resolution operation supports power stage audio performances with SNR 110dB and THD+N 0.01%. The D2-926xx devices are provided in two package and feature configurations which include the 128-pin DAE-3, and the72-pin DAE-3HT. Both the DAE-3 and DAE-3HT provide identical performance and enable an extremely flexible platform for feature rich and cost-affordable quality audio solutions, which benefit from the addition of Class-D amplifiers and DSP audio processing. The 12 integrated digital PWM controllers can be used in a variety of multi-channel audio system configurations, supporting powered as well as line outputs. Fully protected amplifier control provides efficient and clean Class-D power output support. Applications ? DTV and Blu-ray Soundbar ? DVD and Blu-ray Home Theater Systems ?
