I'm the original owner of this superb usb -> spdif converter.Works flawlessly, in mint condition .
USBridge is a true high speed USB Audio Class 2.0 to standard S/PDIF digital signal converter. USBridge is powered by USB line itself, so no further power input is needed.USBridge uses C-Media's CM6631 as main chip.
C-Media is a leading USB audio specialist in the world with excellent reputation for years.
Sampling frequencies (kHz): 44.1, 48, 88.2, 96, 192
Resolution (bits): 16, 24, 32(*) bits
Inputs: USB 2.0, Outputs: S/PDIF x1 (RCA) ,Optical Toslink™ x1, I2S (RJ-45)
S/PDIF transmitter: 3.3V LVCMOS with 24mA current capability (EIAJ CP1201, IEC-60958 interface standards)
I2S output voltage: 3.3V CMOS with 35mA current capability on each line
Power consumption: Standby:141mA, Operating:148mA
Since USBridge is in asynchronous operation, additional oscillators are used for USBridge as the more accurate clock sources and to achieve lower digital signal jitter. 49.152MHz is for 48/96/192KHz sample rate data and 45.1584MHz is for 44.1/88.2/176.4KHz data. These oscillators are specially ordered by Mhdt Labs for 10 ppm status.
