D2-92683-QR集成電路（IC）的音頻專用規(guī)格書PDF中文資料

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.
