Major Tech Tdm8 is a USB audio interface that provides a native 24/192kHz multi-channel (10×10) USB audio to Toslink/I2S/ADAT/TDM interface. It is powered by USB or 5Vdc external supply via header and has a 300mA requirement. The USBStreamer is a miniature 24/192 multi-channel USB to Toslink/ADAT/TDM & I2S interface. It is packaged on a tiny PCB of only 2.4″ by 1.4″ (40x62mm), making it the perfect fit for OEM integration or as an element of a customized high performance A/V product .
The TDM interface is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern . The TDM interface has not been standardized and there can be variants between the TDM formats .
