The XMOS L2 processor in this product provides receive and transmit of digital audio in various formats: USB, AES3 single and dual wire, S/PDIF, TOSLINK, ADAT (+ SMUX). USB may be synchronized to any of the inputs as well as Word Clock. USB interface permits playback of PCM sample rates up to 192kHz as well as DSD and dual-rate DSD.
The program was largely derived from the elements of the L2 MultiChannel reference design. Some optimizations include: greatly improved jitter performance of S/PDIF, AES3 and ADAT clock recovery, elimination of USB explicit feedback, successful receive of 192kHz AES3 "black", DSD.
Clock jitter performance if further imporved by a secondary VCXO-based PLL, which is typical of Grace Design monitoring products.
