Ordering number : EN*5059A CMOS LSI LC89602 Audio Decoder LSI for Mini-Disk Playback Preliminary Overview The LC89602 is an audio decoder LSI for mini-disk playback units. This LSI implements the processing that precedes the D/A converter in playback-only mini-disk players. That is, the LC89602 receives data in sound frame units from a mini-disk data decoder LSI (such as the Sanyo LC89610), expands the audio signal and decoder that signal directly to a D/A converter. This audio expander LSI accepts audio data that has been compressed by a factor of about 5 to 1, and expands that data to audio data that is equivalent to that from a CD player, namely 16-bit quantized data with a 44.1 kHz sampling frequency.
