Overview
SM5866AS D/A Converter for DSD and PCM OVERVIEW The SM5866AS is a D/A converter compatible with both the DSD SACD signal format and the PCM CD/DVD-Audio and similar formats.
DSD employs a 1-bit data stream, from a high-order ∆Σ conversion at 64fs (fs = 44.
1kHz), that contains high-level quantization noise in the high-frequency band above 20kHz.
The SM5866AS, in DSD reproduction, has a DSD-dedicated FIR digital filter that attenuates the DSD quantization noise in the digital domain, and the resulting multi-level signal is D/A converted.
In PCM reproduction, an oversampled PCM signal input, provided using a SM5847AF or similar digital filter, is converted to a multi-level signal by the 3rdorder...
