SM5819HQ
6-channel DSD-PCM Converter
The SM5819HQ is a 6-channel DSD data (64fs) to 4fs, 2fs or fs PCM data converter. During conversion, decimation filtering is performed using a filter with selectable fixed coefficients (3 sets). Also, DSD inputs and PCM outputs are available for use in master/slave clock mode operation, in a wide range of system configurations, making it easy to construct a multi-channel DSD/PCM reproduction system.
