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.

DESCRIPTION
Master Clock Select : Selects the ratio between the input I2S
sample frequency and the input clock.
The STA306 will support sample rates of 32kHz, 44.1kHz, 48Khz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz.
Therefore the internal clock will be:
– 65.536Mhz for 32kHz
– 90.3168Mhz for 44.1khz, 88.2kHz, and 176.4kHz
– 98.304Mhz for 48kHz, 96kHz, and 192kHz
The external clock frequency provided to the XTI pin must be a multiple of the input sample frequency(fs). The
relationship between the input clock and the input sample rate is determined by both the MCSx and the IRx (In-
put Rate) register bits. The MCSx bits determine the PLL factor generating the internal clock and the IRx bits
determine the oversampling ratio used internally.

IR0 Interpolation Ratio Select : Selects internal interpolation ratio based on input I2S
IR1 sample frequency
The STA306 has variable interpolation (oversampling) settings such that internal processing and DDX output
rates remain consistent. The first processing block interpolates by either 4 times, 2 times, or 1 time (pass-
through). The IR bits determine the oversampling ratio of this interpolation.
