ORDERING NUMBER: STA306
DESCRIPTION
The STA306 is a single chip solution for digital audio
processing and control in multi-channel applications.
It provides output capabilities for DDXTM (Direct Digi-
tal Amplification). In conjunction with a DDXTM power
device, it provides high-quality, high-efficiency, all
digital amplification. The device is extremely versatile
allowing for input of most digital formats including
192kHz, 24-bit DVD-Audio.
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 DDXTM outputs. 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.
The serial audio data interface accepts many differ-
ent formats, including the popular I2S format. STx-
channels of DDX processing are performed.
