Overview
The NB7NPQ7222M, produced by onsemi, is a 3.3 V dual-channel, high-gain linear redriver designed for USB 3.2 Gen 1 and USB 3.2 Gen 2 applications. This device supports data rates of both 5 Gbps and 10 Gbps, making it suitable for a wide range of high-speed USB applications. It compensates for signal integrity degradation caused by PCB traces, transmission cables, and inter-symbol interference (ISI) through adjustable equalization and flat gain amplification. The device features automatic receiver termination detection, integrated input and output termination, and is hot-plug capable. It operates across the industrial temperature range of –40°C to 85°C and comes in a compact 3 x 3 mm UQFN16 package.
