AK4117
AK4117
Low Power 192kHz Digital Audio Receiver
GGDESCRIPTION
GGFEATURE
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.
