PRODUCT DESCRIPTIONThe
Sonore DIY USB Interface is a high-performance DXD/DSD128 capable asynchronous USB interface designed for DACs using the ESS Sabre chip. The asynchronous USB receiver is powered from USB allowing for complete isolation of the oscillators, re-clocking and oversampling/filtering (including ground) from the source. Crystek CCHD series ultra-low phase noise clocks are used for the lowest possible jitter. On the "clean" side of the board, the Crystek oscillators (45.1584/49.152 MHz), the FPGA running the oversampling filter (OSF) and the re-clocking circuit, are powered from a user-provided ~5 VDC source.
A unique feature of this interface is the (optional) onboard OSF. This filter oversamples to 352.8/384, using specially developed proprietary digital filters. The filter design takes advantage of the high power available in the FPGA to incorporate a sophisticated partial minimum phase filter, which greatly reduces pre-ringing, while still providing excellent stopband rejection (anti-aliasing).
The USB Interface can also be used with other I2S/DSD DACs.
