LHY AUDIO UIP-LITE USB 2.0 Isolator and Purifier

The LHY Audio UIP-Lite is a USB isolator 2.0 designed to physically separate a source, computer or streamer, from a DAC, while maintaining high-speed audio data transmission. Based on the ADuM3165 chip, with 3.75kV RMS isolation, it supports a 480Mbps data rate and streams up to DSD512 and PCM 768kHz.

Its power supply, regulated by LT3042 and PNP, delivers noise below 1μV at idle and 20μV under a 2A load; secondary stabilization accompanies the 5V 3A output. This architecture aims to limit interference from USB power, while a ground switch allows selection between isolated ground and connected ground in order to address ground loops responsible for hum or buzz.

A low-jitter silicon oscillator contributes to the timing accuracy of the signal. Compatible with computers, streamers, USB DACs and USB flash drives, the UIP-Lite is placed between the source and the USB device to isolate their link while ensuring audio data transfer.
