DDX Multi-channel Digital Audio Processor 1.0 GENERAL DESCRIPTION The DDX-8001 is a single chip solution for digital audio processing and digital amplifier control, featuring output capabilities for DDX® (Direct Digital Amplification). In conjunction with a DDX® power device, it provides highquality, high-efficiency, all digital amplification. The device is extremely versatile allowing for input of nearly all digital formats including 6.1/7.1 channel, 192kHz/24-bit DVD-Audio, and SACD. In 5.1 applications the additional two channels can be used for line-out or headphone drive. Also provided in the DDX-8001 are a full assortment of digital processing features. This includes up to 10 programmable 32-bit biquads (EQ) per channel, bass/treble tone control, and dual 8-input mixing blocks per channel. Automodes™ enable a time-to-market advantage by substantially reducing the amount of software development needed for certain functions. This includes all possible 5.1 bass management configurations with simple large/small/off control settings. New advanced AM radio mode solves one of the most common concerns using switching power amplifiers. The serial audio data input and output interfaces accept all possible formats, including the popular I2S format. Eight channels of DDX® processing are provided with capabilities of controlling the output switching frequency or modulation. This high quality conversion from PCM audio to DDX’s patented tri-state PWM switching waveform provides over 100dB SNR and dynamic range. The DDX-8001 is a 4th generation DDX® controller and is uniquely suited for the most demanding applications, providing an audiophile experience without parallel. Specifications are subject to change without notice. 129 Morgan Drive, Norwood, MA 02062 voice: (781) 551-9450 fax: (781) 440-9528 CONTROLLED DOCUMENT: P_903-000040_Rev19 DDX-8001 Data Sheet.doc email: [email protected] Page 1 of 49 DRN: PRELIMINARY DDX-8001 Table of Contents 1.0 GENERAL DESCRIPTION .......................................................................................................................................1 1.1 Pin Function............................................................................................................................................................4 1.2 ABSOLUTE MAXIMUM RATINGS........................................................................................................................6 1.3 THERMAL DATA ...................................................................................................................................................6 1.4 RECOMMENDED DC OPERATING CONDITIONS ............................................................................................6 1.5 PIN DESCRIPTION ...............................................................................................................................................7 1.6 AUDIO PERFORMANCE ......................................................................................................................................9 1.7 PIN CONNECTION (Top View)...........................................................................................................................11 2.0 DDX-8001 I2C BUS SPECIFICATION....................................................................................................................12 2.1 COMMUNICATION PROTOCOL........................................................................................................................12 2.2 DEVICE ADDRESSING.......................................................................................................................................12 2.3 WRITE OPERATION ................
