Digital Audio Interfaces

The AK410X/1X series is a 24-bit digital audio transmitters/transceivers/receivers. The channel status supports both consumer and professional formats and the AK410X/1X series has automatic detect function of Non-PCM data streams such as AC-3 and MPEG, capable to realize a AC-3 system with a multi-channeled CODEC. Dedicated parallel pins or serial µP interface is available for setting the device. The AK410X/1X series is housed in a small package, saving board space.

AK4118A: Multi Functional Digital Audio Interface with Ultra-low Jitter PLL

The AK4118A is a digital audio interface IC that is designed for professional and high-end consumer audio equipments. The receiver section (DIR) generates a master clock for the local digital audio interface from bi-phase data signals. Standard digital audio data streams are supported, including AES3, IEC60958, S/PDIF and EIAJ-CP1201. The AK4118A achieves industry-leading performance, utilizing an ultra-low PLL with jitter measured under 50ps rms. The clock generated by this highly accurate PLL greatly improves the performance of data converters such as an audio DAC, and it enables superior sound quality for high-end digital audio systems.
