| ASAHI KASEI [AK4114] AK4114 High Feature 192kHz 24bit Digital Audio Interface Transceiver GENERAL DESCRIPTION The AK4114 is a digital audio transceiver supporting 192kHz, 24bits. The channel status decoder supports both consumer and professional modes. The AK4114 can automatically detect a Non-PCM bit stream. When combined with the multi channel codec AK4527B or AK4529 , the two chips provide a system solution for AC-3 applications. The dedicated pins or a serial µP I/F can control the mode setting. The small package, 48pin LQFP saves the system space. *AC-3 is a trademark of Dolby Laboratories.
