– audiophile USB Audio output for USB DACs & USB-to-S/PDIF converters
– ultra low noise design for noise sensitive audio applications
– ultra low noise linear regulators and high quality filters
– high precision ultra low phase noise oscillator
– uDP720201 NEC controller
– two USB 3.0 connectors supporting Low Speed (1.5 Mbps), Full-Speed (12 Mbps), Hi-Speed (480 Mbps) and Super-Speed (5 Gbps) data rates
– 5V for USB devices can be supplied from a PC’s power supply via an HDD LP4 connector or from an external power supply via a power jack connector
– for noise sensitive applications the 5V USB power can be filtered by two onboard high performance filters with PSRR better than 90dB at 10kHz
– in case external PSU is of very high quality, it is possible to bypass the filters and pass 5V USB voltage from the external PSU directly to the USB connectors
– for self-powered USB devices a 5V power is not required for the card operation
