Topping U90 Digital Interface USB to I2S LVDS AES SPDIF Accusilicon 32bit 768kHz DSD512

Multiple interfaces output

Topping U90 has 1x IIS, 2x AES, 2x coaxial, and 2x optical output.

It is suitable for both domestic and industrial applications.

IIS high compatibility

In order to be compatible with different brands of different IIS transmission definitions, U90 is equipped with 4 sets of switches to set the IIS pin definitions, which can be compatible with most other brands of IIS definitions through reasonable setting. It is worth mentioning that the U90 defines a mute pin is IIS transmission. When used with other Topping DACs, it can greatly reduce the pop noise when switching the sampling rate.

Ultra low jitter

U90 uses a femtosecond crystal oscillator and CPLD to process the clock and optimize the digital signal, achieving incredible jitter suppression.

Built-in USB isolation

The built-in USB isolation can effectively eliminate the noise introduced by the ground loop.

12V Trigger

U90 also provides a 12V Trigger interface. When used with other devices with 12V Trigger interface, U90 can be used to control other devices to turn on and off. It greatly facilitates the use.
