The M3A-HS64G02 includes a 96 KHz 24-bit D/A converter with DIT (AK4353, Asahi Kasei EMD Corporation).
AK4353, D/A Converter
SH7264 IIC3, SSIF, and I/O ports control AK4353.
• SH7264 IIC3 (Channel 1): Accesses the AK4353 registers to initialize AK4353, format data, and configure the attenuator
• SH7264 SSIF (Channel 0): Outputs the audio data
• SH7264 I/O ports (PK10): Powers down AK4353 at low
Powers up AK4353 at high
Note: The M3A-HS64 allows for selecting 12.2880 MHz or 11.2896 MHz as the AK4353 system clock.
