The SM5816AF is a 6-channel DSD data to 6-channel 8fs or 2fs PCM data converter IC. During conversion, decimation filtering is performed using a filter with selectable fixed coefficients (4 sets) or optional filter coefficients that are written to the built-in RAM. Also, DSD input/outputs and PCM outputs are available for use in master/slave mode operation, in a wide range of system configurations, making it easy to construct a multichannel DSD/PCM reproduction system.
