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.
