Clock precision

The DAC IC function is to convert digital data in analog. To perform this function the DAC need to made two main tasks: convert the digital number in an analog voltage or current with a best precision related at the number of bits available place this analog value with the best precision in the time […] Read more

USB optical coupling

The modern DAC chip have a noise floor very low at the limit of the measurement instrumentation. It is very important to take care to avoid any unwanted noise coupling. With the USB port we connect the DAC at a computer; noise come from the ground connection and, if directly coupled at the ground plane […] Read more

DSD native vs DoP

On the most recent USB port it is possible to transfer DSD digital audio data. DSD is the digital audio coding used for the SACD format. On a USB we can transfer DSD, DSDx2, DSDx4 so data at a speed like the one of a SACD but also at two or four times fast so […] Read more

USB2.0 High speed port

In the new DAC generation the USB port is foundamental for the reproduction of the hi-res digital formats. Standard digital audio transmission protocol like SPDIF and AES/EBU are limited in the signal transmission. USB port allows the connection of the DAC at a computer or a media transport for the reproduction of hi-res music in […] Read more
