ASAHI KASEI [AKD4358-SC] AKD4358-SC AK4358 Evaluation board Rev.0 GENERAL DESCRIPTION The AKD4358-SC is an evaluation board for the AK4358. The AK4358 accepts up to192kHz PCM data and 1-Bit DSD data making it ideal for a wide range of applications including DVD-Audio and SACD. The AKD4358-SC has a digital audio interface that can interface with digital audio systems via opt-connector or RCA connector. The AKD4358-SC also has several ports allowing you to interface the AK4358 to external devices such as a DSP, DSD processor or AC3 decoder.
