INTRODUCTION

The STA310 is a fully integrated multi-format audio decoder. It accepts as input, audio data streams coded with

all the formats listed above.

2.1 Inputs and Outputs

2.1.1 Data Inputs

- Through a parallel interface (shared with the control interface)

- Through a serial interface (for all the I2S formats)

- Through a S/P DIF (SPDIF or IEC-61937 standards).

- Trough a second, independent,I2S (for application like i..e. Karaoke mixing).

2.1.2 Data outputs

- The PCM audio ooutput interface, which provide:

PCM data on 4 outputs:

• Left/Right,

• Centre/Subwoofer

• Left Surround/Right Surround.
