Overview
The NB7NPQ7022M, produced by onsemi, is a 3.3 V dual-channel, high-gain linear redriver designed for USB 3.1 Gen 1 and USB 3.1 Gen 2 applications. This component is engineered to compensate for signal integrity degradation caused by PCB traces, transmission cables, and inter-symbol interference (ISI). It achieves this through adjustable levels of equalization at the input receiver and flat gain amplification on the output transmitter. The device operates within the industrial temperature range of -40°C to 85°C and comes in a compact 3 x 3 mm UQFN16 package.
