TOPPING U90 USB Bridge
Next-level IIS control
Take control of IIS pin definitions with the TOPPING U90 USB Bridge. Use the four switches on the back plate to select the right IIS phase, MCLK selection, DSD flag, and IIS DSDR.
With seven outputs for IIS, AES, coaxial, and optical, the U90 can act as a bridge for multiple DACs or other destinations. It supports up to 32bit/768kHz via IIS-LVDS and up to 24-bit/192kHz for AES, optical, and coaxial.
Adding components to your audio chain is a double-edged sword. Better sound on the one hand, more potential for jitter on the other. Luckily, the U90 uses its own femtosecond crystal oscillator and CPLD to process the clock and optimize the digital signal, so you’ve got nothing to worry about.
Built-in USB isolation
If you experience hum in your audio system, the U90 may help. Designed with a built-in USB audio isolator, it’s designed to electrically isolate itself and the rest of your system from your source. It eliminates ground loop noise by as much as 50dB in real-world scenarios.
The U90 comes with a 12V trigger on the back panel. This simple jack lets you create a network between any units that also feature a 12V trigger. When connected, it makes one product control the power of the other products in the system. When you turn on one unit, the rest of the system comes on automatically.
