... OVERVIEW The AD1953 evaluation board (EVAL-AD1953EB) permits testing and demonstration of the AD1953 3-channel, 24-bit SigmaDSP audio processor. An input signal is required in either optical or coaxial S/PDIF format, or directly via one 2 of three 10-pin headers left-justified, right-justified, or DSP modes. The internal signal processing program and parameters of the AD1953 can be controlled by a 25-lead SPI interface to a computer’ ...
