AK4117
Low Power 192kHz Digital Audio Receiver
GENERAL DESCRIPTION
The AK4117 is a S/PDIF AES/EBU receiver supporting sample rates up to 192kHz and resolution up to
24-bit. The integrated channel status decoder supports both consumer and professional modes. The
AK4117 can automatically detect a Non-PCM bit stream. Combining the AK4117 with a multi-channel
codec such as AKM’s AK4527B or AK4529 can create a complete AC-3 system. Mode settings can be
controlled via microprocessor serial interface. A low power mode is available for normal speed modes
and the small 24pin VSOP package saves board space.
*AC-3 is a trademark of Dolby Laboratories.
