The SPDIF-Rx-Pro (CWda14) is a digital audio receiver IP core supporting the SPDIF, AES3 and IEC60958 standards and also adds hardware support for the IEC61937 and SMPTE 337M standards for non-PCM (compressed) audio. This purely digital clock and data recovery method dispenses the classical analog PLL at the input reducing the receiver cost. The Modular structure of the CWda14 allows enhanced functionality for specific applications by using the optional Add-on-Modules (AOM). Coreworks offers a broad range of SPDIF receivers and transmitters targeted for variety of audio applications.
