DESCRIPTION

Auto-Mute

The STA308 is a single chip solution for digital audio

processing and control in multi-channel applications.

It provides output capabilities for DDX^TM(Direct Digi-

tal Amplification). In conjunction with a DDX^TMpower

device, it provides high-quality, high-efficiency, all

digital amplification. The device is extremely versatile

allowing for input of most digital formats including 6.1

channel and 192kHz, 24-bit DVD-Audio.

■ Selectable Serial Audio Data Interface

■ Bass/Treble Controls

■ Channel Mapping of any Input to any

Processing/DDX^TMChannel

■ Active Crossover Capability

■ DC Blocking Selectable High-Pass Filter

■ Selectable Bass Management on Channel 6

■ Selectable Adjacent Channel Mixing Capability

The internal 24-bit DSP allows for high resolution

processing at all standard input sample frequencies.

Processing includes volume control, filtering, bass

management, gain compression/limiting and PCM

and DDX^TMoutputs. Filtering includes five user-pro-

grammable 28-bit biquads for EQ per channel, as

well as bass, treble and DC blocking. External clock-

ing can be provided at 4 different ratios of the input

sample frequency. All sample frequencies are up-

sampled for processing. Each internal processing

channel can receive any input channel, allowing flex-

ibility and the ability to perform active digital cross-

over for powered loudspeaker systems.

■ Selectable DDX^TMHeadphone Output on

Channels 7 & 8

■ Selectable Clock Input Ratio

■ Selectable De-emphasis

■ Selectable DDX^TMTernary, or Binary PWM

output

■ AM Interference Reduction Mode

■ I2C Control

The serial audio data interface accepts many differ-

ent formats, including the popular I2S format. Eight

channels of DDX processing are performed.
