Introduction

The STA306 is a single chip solution for digital audio processing and control in multi-channel applications. It provides output capabilities for DDX (Direct Digital Amplification). In conjunction with a DDX 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 DDX outputs. Filtering includes five user-programmable 28-bit biquads for EQ per channel, as well as bass, treble and DC blocking. External clocking can be provided at 4 different ratios of the input sample frequency. All sample frequencies are upsampled for processing. Each internal processing channel can receive any input channel, allowing flexibility and the ability to perform active digital crossover for powered loudspeaker systems. The serial audio data interface accepts many different formats, including the popular I2S format. STx channels of DDX processing are performed.
