High-speed and high-reliability performance for stable data transmission. Purifies surges and noise interferences in USB transmission. Isolates power interference entering through device GND. Functions as a USB repeater for long-distance device relaying. Supports USB 2.0 (Full Speed) and (Half Speed), with transient common-mode interference resistance > 100kV. The ISOUSB211 chip is characterized by high speed and high reliability. It is mainly used to purify various surges and noise interferences brought by USB transmission. It can provide a more stable data transmission environment for USB audio devices and isolate power interference that enters through the device GND. Besides purification, it is also a USB repeater. It is used for relaying USB upstream and downstream devices over long distances. It is very suitable for PC HIFI and car users. Isolation voltage: 1500V. Two power supply methods: 1. Self-powered by the upstream USB device. This isolator is equipped with a Murata isolated power supply module, which can provide a continuous current of 300mA. 2. A high-quality power supply can be connected through the DC-5.5 2.1 power interface for enhanced power supply.
