Digital Audio Output Interface
The Digital Audio Output Interface pins are described in
nects to an audio PCM DAC. The sample rate and the size of the samples are programmable to accommo-
date any commercially available DAC. The CS7410 has two data output pins, for up to 4 channels of PCM
output, and a separate output pin to simultaneously output IEC-958 encoded data (either compressed or
uncompressed).
∆Σ Modulator Interface
The
tor, which outputs two differential digital signals on four pins. These outputs are design to drive an external
op-amp based integrator circuit (contact Cirrus Logic Applications Engineering for details) .
