The AK4115 is AKEMD's highest performance AES/EBU transceiver. It is referred to as AES/EBU since it is intended for professional audio applications - S/PDIF is generally used for consumer applications. The AK4115 contains a very high performance PLL that has less than 70ps rms of jitter. The AK4115 offers several unique features that are not included in the earlier generation AK4114. It has two crystal oscillator circuits, which enable a complete clocking solution capable of generating any multiple of 44.1kHz or 48kHz master clocks. The receiver and transmitter can operate fully asynchronously, where the transmitter can be the matter. The device can lock to either an AES clock or the word clock (studio sync). There is an 8:1 input selector with support for one fully differential (balanced) input. The output transmitter has an integrated differential RS422 output. The AK4115 is available in 64-pin LQFP package.
