SM5819

The SM5819AF and SM5819HQF are 6-channel DSD data (64fs) to 4fs, 2fs or fs PCM data converters. 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. SM5819HQF filter cut-off are set for highest quality and suitable for data acquisition
