DESCRIPTION

The STA310 is a fully integrated Audio Decoder ca-

pable of decoding all the above listed formats.

Encoded input data can be entered either by a serial

(I2S or SPDIF) or a parallel interface. A second input

data stream (I2S) is available for micro input.

The control interface can be either I2C or a parallel 8-

bit interface. No external DRAM is necessary for a to-

tal of 35ms surround delays.
