DIGITAL AUDIO INTERFACE
AK4115
High Feature 192kHz 24-Bit DIR with 8:3 Selector & DIT
The AK4115 is a 24-bit stereo digital audio transceiver that supports sampling rates up to 216kHz. The channel status bit decoder supports both consumer and professional modes and can automatically detect Non-PCM bit streams such as Dolby Digital or MPEG. The AK4115 supports a wide array of features a couple of them being; differential cable driver and receiver support, and an internal PLL that can support clock sources such as bi-phase and “word clock”. Control of AK4115 is achieved though a µP or pin-strapping (parallel mode) and it is packaged in a space- saving 64pin-LQFP.
